From a person who lives in the arctic: If you are outside in cold weather and you are freezing, but all of a sudden feel really warm with no explanation as to why DO NOT REMOVE ANY CLOTHES. You are about to die and your body is spending it’s very last energy on heating you up. Seek shelter and warmth immediately even if it feels like you are boiling hot. People have been found freezing to death in their underwear not far from civilization because they believed they were warm

If you ever have to touch an electrical wire that you’re not sure is live or not, touch it with the back of your hand. If you touch it normally, the electricity will make your muscles contract, and you’ll automatically grab on to the wire tighter and tighter until you’re dead.

As long as you are not encircled or without escape possibilities never go for a fight. A fight is by definition an uncontrollable situation for you. The human body is very fragile. You can easily end up at the cemetery or in jail, no 200 bucks are worth that. Even professional fighters avoid fights on the street. This is even more the case when knifes are involved. The old saying goes: the looser of a knife fight dies on the sidewalk, the winner in the ambulance.

If you're in a crowd that's packed almost uncomfortably tight, ask yourself: If my shoe fell off right now, would I be able to retrieve it? Or would I just never see it again? if the latter, GTFO of that crowd.

An "Impending Sense of Doom" is a legitimate symptom and you should hurry yourself to the ER, especially when accompanied by other symptoms such as chest pains, dizziness, numbness in limbs, etc...

We all know the symptoms of a heart attack as pain in the chest and/or the arm closest to the heart (usually left, sometimes right). But women tend to have pain in their stomach instead. There are also cases of people thinking they have pain in their back which turned out to be their heart.

If you are ever being chased by a polar bear get completely naked and drop your clothes on the ground as you run away. Polar bears have really bad ADD and will firmly inspect your clothes before chasing you again

If you are in a big crowd with a group and you lose track of them, call out your own name to find them, not theirs. I don’t know why it works, but people are more attuned to hearing their friend’s name yelled in distress than their own. I’ve had several opportunities to test it out, and I swear it works every time.

If you are injured or need help in a crowded place direct your pleas to a specific person. Otherwise people tend to think that someone else will help, it’s known as the bystander effect. In an emergency every second can be crucial, give specific instructions to specific people

If you or your kid is eating fruit and they complain about it tasting 'fuzzy,' 'hairy,' or something along those lines, it means that they are allergic to it. You'll want to schedule an appointment with their pediatrician to schedule an allergy test.

Don’t leave a suicidal person alone, no matter how jolly he looks that moment.

Don’t remember where I learned it, but the air begins to smell like ozone before lightning strikes, so if the air starts smelling kind of like chlorine during a storm, it means lightning might be about to hit the area you are standing in

Don't mix window cleaner and bathroom cleaner

If you smell Natural Gas in your house, don’t turn on lights, appliances or use the phone inside. A spark could cause an explosion.

If you're choking and alone, you can throw yourself onto the edge of furniture, like a chair or couch or table. A blow like that onto your midriff is similar to a heimlich manoever and can dislodge whatever is stuck in your trachea.

If anyone is ever getting electrocuted around you do NOT touch them directly. Instead use some sort of object to get them away from the object they are holding or touching. You can use a belt wrapped around a waist (again be careful not to touch them), a broom, mop, fast moving office chair, hell if its that serious you can drop kick them out of contact. Can't tell you how many people have gotten themselves electrocuted grabbing someone stuck to something.

Kangaroos can't hop backwards I don't care how drunk you get, you and a friend will be on vacation in Australia 5 years from now, he'll get attacked and you'll instinctively yell "get behind him!"

If something is squirting blood, that’s an arterial bleed. You need a tourniquet. When applying a tourniquet, go high and tight. How tight? It’s gonna hurt. You’ll know the TQ is working when you can no longer feel a pulse on that arm/leg. Tourniquets CAN be improvised, but it is highly recommended to use a proper CAT tourniquet if available. Make sure to record the time (preferably in 24 time such as 0930) that the tourniquet was applied.

Fire spreads fast. **Really** fast. As in: It can go from a wastebasket to an entire room in three minutes flat. If you find something in your house is on fire and you don't have something immediately to hand (such as a fire blanket or extinguisher), get everyone out immediately. Don't even stop to find your phone.

When doing CPR chest compressions pace them to Stayin Alive by the BeeGees

Oil-soaked rags (from stain, oil-based paint, changing the oil in your car, etc.) can spontaneously self-ignite if not disposed of properly. Don’t just throw them in the trash. It’s better to dry the rags out completely, then submerge them in water, then dispose of them however/wherever your municipality collects hazardous materials.

Always wear an anti static bracelet in applicable situations. Building a PC or even changing components is one.

Keep an eye out when you wipe. Colorectal cancer which used to be prevalent in older men is showing up in younger and younger people. So if you see blood bring it up to your doctor. I'm currently dealing with it and I don't wish this on anyone.
