10 BIZARRE Body Signs You SHOULDN'T Ignore!

Skin rashes, uncontrolled laughing, wrinkled earlobes? And more. Today we are breaking down some truly bizarre ways that your body is trying to tell you something is potentially wrong with it.

1. Metallic Taste in Your Mouth

Does your mouth taste like you just sucked on an old coin? Chomped on some pennies? Well, this common metal mouth type of taste could be a side effect of a variety of different medical issues. For starters this could be a sign of heartburn or indigestion, this could be due to bad oral hygiene or say a reaction to a medication or something. Or heck I’ve even had patients who got bit by rattlesnakes who experienced this coppery type of flavor.

But if you experience a recurring metallic taste in the mouth this could also be signifying other serious illnesses like chronic liver problems, undiagnosed diabetes, or even Kidney disease. You see when your kidneys haven’t been functioning properly for a while, a substance called urea builds up in the bloodstream causing a medical condition called uremia. And one of the common symptoms of having uremia is a metallic taste in the mouth.

Now if you are otherwise healthy and it's just a one-off metal tang that comes on, it's probably pretty benign, but if you experience this bizarre metal taste along with changes in urination and back pain, definitely follow up with your doctor. If there is an underlying serious medical condition you need to treat it sooner rather than putting off until later.

2. Skin Tags

No they aren't warts, Skin Tags however are those harmless little skin flaps or extra skin that grow most often on the areas of your body that rub together or against your clothing. Common areas include the underarms, neck, groin, and face. Now while usually friction can produce these unwanted extra pieces of skin not to freak you out or anything, there could also be several underlying medical conditions that can be correlated to skin tags. Things like: Obesity, Crohn's disease, High blood pressure, PCOS and even Diabetes. Diabetes for instance is a health condition that affects how your body turns food into energy and can cause chronic high blood sugar levels. So what's the connection to skin tags? Researchers in several studies have determined that having numerous skin tags may be a sign of insulin resistance and is more prone to developing type 2 diabetes. So pay close attention if you find yourself suddenly getting more of these skin tags on your body. Additionally, women who experience fluctuations in their hormone levels for instance during pregnancy or as they age may also be more prone to skin tags.

3. Aching Jaw

Jaw pain is no joke. Besides the obvious culprit like a sports injury, Persistent tenderness that can radiate to other parts of the face, definitely a red flag. This Aching pain can also be a sign of other pressing medical issues, things like: Sinus infection, tooth problems, blood vessels or nerve issues. As well as a total mouth full of a condition called: temporomandibular joint disorder or TMJ for short. This is where the joint here acts sort of like a sliding hinge connecting your jawbone to the skull and any issue with this mechanism can certainly cause pain and discomfort. You’ll definitely want to contact your doctor or Dentist if you suspect you may have TMJ.

Now that being said, another often overlooked medical condition that also may be linked to an aching jaw is actually Lyme disease. Lyme is a tick-borne illness caused by deer ticks that carry bacteria. Typically lyme disease first causes a bullseye pattern rash, flu-like symptoms among other joint pain and weakness in the body. But if you're suffering from chronic pain or jaw aches that come and go, ask your doctor if lyme disease could be a possible issue. Although one of the harder ailments to diagnose this could potentially be an underlying culprit for many persistent pains in the body such as jaw aches.

4. Itchy, Blistery Skin Rash

I’m sure everyone watching this has experienced some sort of suspicious rash on the body at least once in their life. But if you find yourself with an itchy, blistery reaction that breaks out specifically on the elbows, knees, butt, back or even scalp you’re going to want to pay close attention. Although yes this could be a sign of or look awfully close to eczema, a dermatitis condition that causes dry, itchy and inflamed skin. But, this rash could also be a sign of a more serious issue called Celiac disease.

Celiac disease is an autoimmune condition in which ingesting even the tiniest amount of gluten causes your body to freak out and attack its own small intestine. Usually, a person with Celiac may experience classic symptoms like diarrhea, bloating, gas, fatigue, low blood count (anemia), and osteoporosis. But many others who suffer from celiac may have no digestive issues but rather up to 25% of people with celiac may experience this type of rash, known as dermatitis her-pet-iformis.

When someone with celiac consumes gluten, the body releases an antibody known as IgA, which attacks the intestines; sometimes IgA also collects in small blood vessels underneath the skin, triggering the telltale rash. If you find yourself with a similar skin issue, definitely talk to your doctor as they may be able to biopsy the rash and look for antibodies that indicate celiac. From there they will often recommend a gluten-free diet, which should make the skin condition lessen or disappear, and protect your body from other long-term, serious damage of celiac disease, like osteoporosis or small intestine cancer.

5. Lumpy Collarbone

Now im not talking about an old battle wound or collarbone break from a sports injury or falling off your bike or something. Rather If you find yourself with a sudden lump on your clavicle, your body may just be trying to warn you of danger lurking around the corner. Typically swollen lymph nodes usually occur as a result of infection from bacteria or viruses. And they play a vital role in your body's ability to fight off infections.

But located on top of your collarbone near your neck is a lymph node called Virchow’s node. This node can serve as a warning signal for your digestive system. In specific instances, especially on the left side where Virchow's node swells up—a condition called supraclavicular lymphadenopathy or troisier's sign—may be the first indicator of cancer of the stomach, intestines, or colon. So if you find yourself with swelling of this specific node or any lymph node in your body for that matter, please see your doctor as soon as possible. This could turn out to be very serious.

6. Chewing on Ice

You've probably heard the old saying that chewing ice means you're sexually frustrated. Well although that could be true, that's not exactly the medical condition that your body is trying to warn you about.

Chewing ice could be a tell-tale sign of Pagophagia, or more simply a subtype of pica. A mental disorder that involves compulsively eating ice, snow, or ice water.

Now if you find yourself with a strong desire to chew ice and pica is not the culprit this could also be a warning for another bodily issue, That you’re in desperate need of more iron or that you're anemic. Anemia also referred to as low hemoglobin, is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. This can make you feel tired, weak and dizzy, in mild cases, but in more severe cases this could be life threatening. Also if you notice that your hair is thinning out, this could be another symptom of iron deficiency. So if you’re wondering how to get more iron in your day-to-day life, of course you take a supplement. Or rather than chomping on ice, instead try chowing down on foods that are naturally rich in iron like red meat, seafood, beans, spinach and more.

7. You Laugh or Cry Uncontrollably for No Reason

This could mean you have MS. Multiple sclerosis (or MS for short) is a potentially disabling disease of the brain and spinal cord in which the immune system attacks the protective sheath (the myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. But going back to the uncontrolled laughing or crying for a second. This symptom is called pseudo-bulbar affect (PBA), and is a very serious indicator. As it occurs in at least 10 percent of people with MS. And signs and symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with MS may experience numbness, muscle spasms or even worse lose the ability to walk independently among other complications. So if you or someone you know is experiencing this laughing or crying uncontrollably for seemingly no reason, definitely get in touch with your doctor today. This is definitely a warning sign that your body is trying to send to you.

8. Smelling Things That Aren't There

Are you getting a sudden whiff of rotten eggs or say wet dogs? Gross smells, but then you look around and there are no signs of the unpleasant odor culprit in real life. This my friends is a serious indicator that you shouldn't just blow off as a general funk in the dorm room type of smell . Rather phantom smells or Phantosmia as it is medically known is a condition in which your nose catches a scent of something particularly unpleasant but it's not actually there. This is a serious sign that something is off and you need to see a neurologist ASAP. This could be a warning of a more concerning matter such as brain tumor, epilepsy or parkinson's disease. Even if it ultimately just turns out to be your roommate who just refuses to shower, it's better to be safe than sorry. If you are smelling weird phantom odors, schedule an appointment with your doctor immediately.

9. Yellow Eyes

Ever heard of a check engine light on your car? Well, what if I told you that similarly, your body has a check liver light -so to speak? If the whites of your eyes are no longer white but instead turn a bright yellow, the first medical condition that comes to mind is jaundice.

Jaundice is a condition in which the skin, whites of the eyes and mucous membranes turn yellow because of a high level of bilirubin, a yellow-orange bile pigment in your system. Basically when your liver isn't properly breaking down the bilirubin can build up in your system causing things like your eyes to turn yellow. This can be caused by issues like hepatitis, gallstones, and tumors. If this is the case that your check liver light comes on, you'll definitely want to get examined by a doctor, particularly if you have a fever as well.

10. Diagonal Earlobe Creases

Say what? Yes let me repeat that again, Diagonal earlobe creases. I know it sounds like a bizarre mad lib rather than a real medical indicator but humor me take a look at your earlobe, if it has a wrinkle-like line going diagonally down it, you may want to really put some extra attention into boosting your heart health. This visible wrinkle is sometimes called: Frank’s sign and it could be an indicator of coronary artery disease, aka- the most common form of heart disease. According to many studies there is an association or link between these angular ear wrinkles and and the leading cause of death in the United States. So all this to say if you or someone you know has these suspicious ear creases reach out to a health care professional and discuss how you can improve your heart health.

5 MOST PAINFUL Sports Injuries Athletes Can EVER Experience!

Do you watch sports? How about playing them? What is the absolute worst sports injury that an athlete can experience? I see it all the time in the Emergency department, even the most advanced, strongest competitors come in with excruciating pain. And treating these injuries sometimes can leave a patient screaming even more…

And If you’re anything like me who grew up playing soccer (or Football my whole life), you train hard, work out, and compete at an advanced level. Sometimes bad technique, freak accidents, and injuries happen. That’s why today we are discussing and breaking down the 5 most painful sports injuries that can occur both on and off the field. Believe me when I say these are not pretty!

5. Broken Ribs

It doesn’t matter if you are a top Pro Football player getting sacked on the field or you're just riding your dirt bike off a jump and falling the wrong way, our first injury can be agonizing, and feel like it’s never going to end. It hurts when you laugh, when you sneeze, when you sleep, heck even when you breathe. A constant insufferable reminder that your sports career may have just ended, or at least seriously halted. Of course, I'm talking about multiple broken ribs. This injury makes it hard to just manage the normal day-to-day functions that we all take for granted and it could also be very dangerous. I’ll explain.

You see the reason we even have ribs, to begin with, is they are the skeletal protection for the lungs and the organs in your chest cavity. But here's the thing: they also along with the rib muscles expand and contract with normal breathing. So if you shatter or break a rib, say diving in the outfield during a baseball game, every time you take a breath, the broken pieces could be potentially jabbing the surrounding tissue and messing with your breathing. (possibly even puncturing your lung)

And unlike say a broken arm where we just cast it and send you home. Unfortunately, there is no way to fix a broken rib other than time. So the injured patient just has to chill and let it heal on its own for several months until the bone fuses back together.

So, if you break your rib and are in a ton of pain, get to the hospital so we can get some x-rays and make sure no further damage has occurred. Typically the pain management includes ice on the area to relieve the pain, pain medicine like acetaminophen or ibuprofen, and not I repeat not wrapping anything too tight on the area. Also, the patient will want to make sure they are taking deep breaths or doing breathing treatments because they could be at higher risk of pneumonia.

Have any of you ever broken a rib? Let me know in the comments what happened and what that was like for you.

4. Broken Tailbone

Football players, contact sports athletes you name it. Some of you out there may have experienced our next tortuous injury: the broken Coccyx. Yes, I’m sorry to report if you receive a direct blow or trauma to this area of the body you are not only going to be in a whole heck of a lot of pain but you’re also going to be finding yourself with a lot of downtime from your favorite sport and social calendar.

Alright so what is a coccyx and why does it take so long to heal? Commonly referred to as the tailbone, below the sacrum is the coccyx, It is a set of 4 bones and serves as an attachment point for several pelvic and hip tendons. Most of us use this part of our body for so many different functions. So when you injure that area let alone fracture it, you can say goodbye to comfortable sitting, sayonara to sleeping on your back, walking normally, or even going to the bathroom without excruciating pressure to that area. And this super painful and inconvenient road to recovery can unfortunately last months on end.

So how does one know if they have a coccyx injury? Well, the pain for starters but the injury is largely determined by a physical exam of the entire vertebral column as well as x-rays. Also oftentimes in the Emergency Department, a rectal exam may even have to be conducted to see if there is a dislocation or a fracture. Which is no fun for anybody.

To help with pain management we often tell our patients to ice it 15-20 minutes 4 times a day and take anti-inflammatory medication as well as the real secret helper is a cushion "doughnut" pillow to sit on. This cushion has a hole in the middle to prevent the tailbone from contacting the flat surface which will help alleviate some of the pain.

3. Dislocated Shoulder

Gymnasts, skateboarders, and baseball players consider this your warning because our next painful injury is a doozy. The dreaded dislocated shoulder, heck I'll even include a dislocated elbow in this description because no matter if it's your shoulder or some other area of the arm. Plain and simple: this is a painful injury, and for sure you will not be able to move your arm in the injured area.

A dislocated shoulder happens when your upper arm pops out of your shoulder socket. The shoulder is one of the easiest joints to dislocate because the ball joint of your upper arm sits in a very shallow socket. And there are three different types of dislocations, the anterior being the most common. But no matter which way you dislocate your shoulder, you will not be able to move your arm and it will be very painful. Also, the shoulder will suddenly look square rather than round. You may even be able to see a lump or bulge (the top of the arm bone) under the skin in front of your shoulder. If this happens to you it's super important to get to the Emergency department as soon as you can.

As an ER doc in the hospital, what I'll do if you come in with this injury is a: closed reduction or in other words, a procedure in which I'll attempt to put the ball of your upper arm back into the socket.

We try to treat shoulder dislocations immediately because though complications rarely occur, a person could be at risk for limb loss if damaged arteries or veins are not treated within six to eight hours after the injury. So it's super important we treat it right away. Now after it's set back into place, we may splint it, give you anti-inflammatory meds and suggest rehabilitation. Sometimes surgery is required as well but all in all, it usually takes about 12-16 weeks to get back to a normal range of motion in your arm.

2. The Anterior Cruciate

The Anterior Cruciate Ligament. Aka an ACL injury. This is one of the most agonizing pains a player or athlete can experience for sure. Located in your knee, the anterior cruciate (ACL), and other ligaments all are strong bands of tissue that connect your thigh bone, also known as your femur to your shin bone or your tibia. Oftentimes in sports when a player is doing sudden stops or changes in direction movements, jumping, or even landing weird in sports like soccer, football, basketball, skiing, snowboarding you name it. This can put a person at higher risk for an ACL injury.

And the Anterior Cruciate, you can either tear it or sprained it. And it may sound obvious but let me be clear, a tear is when the ligament is actually torn and that can be again either a partial tear or a complete one. As in fully torn. Whereas a sprain is when the ACL is overstretched but not torn.

When you see these sorts of ACL or other ligament injuries of the knee happen on the field it's a sight you won't soon forget. You will see some of the brawniest, strongest athletes in the world clutch their knees in screaming agony. Believe me, I see it in the Emergency Department all the time and it is a painful one that should not be taken lightly.

So how do you know if you have injured your ACL? Well, when the injury occurs often people hear a pop or a snap, and then suddenly they will feel unstable along with an insurmountable amount of pain. Also, a patient usually won't be able to bear weight on that leg. Depending on the severity of the ACL we will often grade the level of severity for instance it could be a level 1 sprain, but anyways f the injury is more severe or even torn completely you will be out of the competition for a while and have to partake in rehabilitation exercises to help regain your strength and stability. Also, surgery may be required to fix it as well. And Most people have a long road to recovery with an ACL tear usually taking six to nine months to recover. Have you or anyone you know torn or sprained their ACL? Let me know what your recovery process was like.

1. The Achilles Tendon Rupture

Yes, basketball lovers, tennis pros, heck even if you're just a normal non-athletic person might be walking downstairs a little too aggressively, listen up because this next heinous injury may just really rock your world and take you out of the competition game! Of course, I'm talking about the Achilles tendon tear or rupture. This can be not only devastating to a player of course but also super painful.

The Achilles tendon is a strong fibrous cord that connects the muscles in the back of your calf to your heel bone. If a person overstretched their Achilles tendon, it can tear. Sometimes you hear the words rupture and tear, they are the same thing, injured tissue that has a cut. But also keep in mind that this injury can be partial or total. If it's a total rupture of the Achilles heel, that means that the tendon has been entirely severed. This is very serious.

But backing up the bus a bit, How does one know if they tore it? Well most commonly if your Achilles tendon ruptures, you may hear that good ol’ handy dandy pop followed by an immediate sharp stabbing pain in your lower leg, the back of the ankle, and you probably won't be able to walk. What's interesting is the foot won't be able to bend down or you won't be able to push off of the injured foot. If you come to the Emergency Department we will probably run some image tests like an ultrasound, or MRI, And then from there decide if you need surgery to repair it or whether we will opt to fix it with nonsurgical treatments. But overall realistically you’re looking at a 4-6 month painful recovery process and physical therapy to get your mobility back from this type of injury.

Also, keep in mind that excessive use or overuse of that tendon through sports and non-stretched types of activity could cause tendonitis in the area and could be a contributing factor. As well as some medications such as certain antibiotics and steroid injections can also weaken the Achilles tendon. But honestly even something as random and simple as accidentally stepping in a pothole or something could cause this injury. So please be careful.

5 DEADLIEST Animal Bites You Can SHOCKINGLY SURVIVE!

What is the absolute worst type of animal bite? Or what’s a bite that seems harmless but that could cause serious damage? I see it all the time in the Emergency room, people come in for all sorts of bites and wild animal injuries. But can one bite actually kill a person? How about a quick chomp paralyzing a patient or causing neurological damage?

It can absolutely happen if not treated right away, that’s why today we are discussing and breaking down 5 different types of animal bites and why you need to treat them or seek help urgently. It could be a matter of life or death.

1. Snake Bite

The temperatures are heating up in certain parts of the world, like here where I live in Southern California and that usually means snakes are more active. You see them when you go hiking, sometimes they find their way in your house, but no matter how you come into contact with one of these slithering serpents, it's best you don't get into a tangle with them because the results could be disastrous. For starters, most average folks are not able to easily identify which snakes are which, out there in the wild. And with that, you may not know if the snake you are locking eyeballs with is venomous or not. So if bitten by any type of snake it's a no-brainer to just use extra precaution and j get to the hospital immediately.

That being said, of course, not all snakes are venomous. Venomous snakes are capable of injecting venom by way of their bite. So let’s pretend for a sec you’re bitten by a venomous snake, which is usually apparent by the two fangs on the snake that deliver two pretty distinct puncture marks to an area of the body. Depending on what type of venomous snake you are bitten by, a person will usually begin to see symptoms immediately that then worsen over time. Realistically you need to get to the hospital as soon as you can but you absolutely want to seek medical attention within 30 minutes. Doctors, if they have it, will administer antivenom. But if a bite is left untreated, your bodily functions could break down and you may experience trouble breathing, severe tissue destruction, paralysis, organ damage, or even death.

Brown snakes for instance in Australia are highly venomous and bites can lead to rapid blood pressure drop, cessation of blood clotting, and cardiac arrest all within just minutes. Here in Southern California, I treat a lot of Rattlesnake bites, which can be fatal for about 1 in 600. Luckily we have an antivenom that can help reduce symptoms but you have to get to the hospital as quickly as you can.

Now one other thing, do not ice a snake bite. This can cause smaller blood vessels to constrict and sometimes produce dramatic tissue damage. If bitten, just focus on getting to the hospital.

2. Ticks

As someone who grew up in the North East, I'm used to having to search for ticks when coming in from wooded areas. But you would be shocked to learn all of the diseases these tiny little pin-sized creatures can carry. Now depending on where you live in the world and which tick species are native to your region, Being bit by a tick could result in a million different ailments. Things like: Anaplasmosis, babesiosis, Colorado tick fever, Lyme disease, encephalitis, Rocky Mountain Spotted Fever, Southern Tick-Associated Rash Illness, Q fever, and more.

Now if you’re like well I have no idea what any of those things are? But they sound scary. They for sure are. These diseases trigger rashes and fever, fatigue, pain, skin ulcers, and neurologic problems, some very severe and some that endure for years. With Lyme disease specifically is more common in the US. I have treated patients who couldn't walk, who had heart problems, and more with later stages of Lyme disease, it’s no joke.

So, If you have a tick bite watch for an expanding red rash or lesion at the site of the tick bite or an unexplained feverish, achy, fatiguing illness within 1 to 4 weeks after the tick bite. If you are concerned, you could even take a picture of the rash and contact your physician. A lot of these have very distinctive patterns, for instance, a bullseye rash pattern could show up.

If you think you are bitten don’t just brush the experience off either, like eh it's just another bite. In areas that are highly endemic to Lyme disease, for instance, a single prophylactic dose of doxycycline may be used to reduce the risk of acquiring Lyme disease.

3. American Alligator

Maybe you’re heading to the South this year to do a little vacationing or heck maybe you even live there. I know I've certainly seen them when I used to live in North Carolina back in college, but an alligator's bite can be extremely serious and life-threatening. I mean talk about a force that could kill something or at least do some serious damage. The bite of an alligator is strong. We’re talking a psi of 2,900 LBS strong or enough to crack a turtle’s shell. So just imagine what it could do to say human skin or an animal’s skin. And not to mention they have 80 sharp teeth to go along with that to easily tear things into pieces.

If you are the unlucky one who gets gnawed on by an alligator we usually treat it as major trauma. I know it may seem obvious with major lacerations and flesh missing, heck possibly even fingers or limbs missing, but even if you didn't lose any of your digits. It’s also important to realize that one could also be at high risk for a soft tissue infection because of the microorganisms that can be transferred from gators.

If you are wondering about the crocodile’s bite, similarly if you find yourself in a run-in with a crocodile and make it out of there, definitely get to the hospital. But the kicker is the force of their bite is said to be even stronger than the gator, so it’s best you just steer clear of these saltwater beasts altogether.

4. The Mosquito

It’s time for the deadliest animal on the list, Their bite alone is responsible for the deaths of more than 400,000 people every year.

I know what you are thinking, a mosquito? Really? But it's true, these little bugs and their bites can mean deadly consequences if not treated accurately. So let’s break this down further shall we?

It’s very rare that you actually feel a mosquito bite you. That’s because the mosquito injects saliva that prevents clotting and numbs the area so you don't usually feel the bite, allowing the mosquito to feed on your blood undisturbed.

And a mosquito’s little pesky bite can transmit a smorgasbord of dangerous diseases to humans. Things like: Malaria, chikungunya, dengue, yellow fever, encephalitis, and Zika Virus. The list goes on. As I said at the beginning of this, more than 400,000 people die every year from malaria alone.

So when to go to the hospital? Anyone bitten by a mosquito who then experiences nausea, fever, swollen lymph nodes, a rash, or a prolonged headache should visit the emergency room. Hospitals will try to figure out which mosquito-borne disease you may be suffering from and offer supportive therapies.

For full disclosure, not every mosquito out there carries some sort of killer disease but you should definitely be on high alert, especially when traveling somewhere new that is known to have these infected mosquitos or high instances of these diseases. For instance, some places in South America, are on higher alerts for Zika Virus and encourage travelers to Practice Enhanced Precautions. Similarly, the highest transmission of malaria is found in Africa, South of the Sahara.

Now if your mosquito bite isn't that serious, just super itchy and annoying, try washing the area with soap and water then ice it a bit. You can even use a mix of baking soda and water on it or any over-the-counter anti-itch cream. People also say honey and aloe vera work. If you want me to do another video on all the most dangerous bug bites in the world of spiders. let me know because I could do a whole video just on bugs and just spider bites alone.

5. Shark

I’ll start with the good news about shark bites. The odds of being killed by a shark are about 1 in 3 or 4 million. In fact, you have a much higher chance of dying from a selfie-related accident than a shark attack but shark bites can be extremely serious and even fatal.

Also, the necessary medical treatment depends on the severity of the shark bite and even what kind of shark the biting will also factor into that. A great white shark for instance has a much more violent bite than say a nurse shark. But regardless of who or what bit you, it's imperative that you get to safety first, so in other words, get out of the water and try to stop the bleeding.

It’s super important to restrict the blood flow, a lot of times that means keeping a wet suit for instance on, it kind of keeps things intact as much as possible and stops a person from bleeding out. And if I didn’t say it already, get to the hospital or seek out medical help as soon as humanly possible.

Now at the hospital obviously the treatment will depend on the severity of the bite but typically we may take a patient quickly to the operating room, remove any dead tissue, course, control bleeding, and clean the wound thoroughly.

Lastly, just some minor shark encounter details to keep in mind. Sharks are attracted to high-contrast colors, and a lot of divers use the phrase “yum yum yellow” for instance talking about sharks’ attraction to certain high-contrast colors. So keep that in mind if you’re out surfing. And if you really have to fend for yourself, gills and eyes are very sensitive. But of course, that's only to be used if you are truly in an emergent situation where you have to go head to head with a shark. Luckily most of us will never have that experience but if you know someone who’s ever had a run-in with a shark let me know in the comments.
