1. If you sink, scream
If one day you find yourself on a sinking ship, and somehow you manage to break free, be careful. Once the air is neutralized, if you are low enough, the water pressure will kill you and your lungs will collapse. To avoid this, shout your way to the surface. No joke, while you swim, you must shout; this will prevent the pressure from killing you.
2. Deep wounds
Do NOT use hydrogen peroxide on deep wounds, as this hinders the healing of the blood. It is fine for small cuts, but NEVER for a deep wound.
3. Neck injuries
When you see someone whose neck has been cut and is bleeding heavily, locate the carotid artery and cover it to stop the bleeding. This will allow emergency services to arrive.
4. In case of fire
Fires spread surprisingly fast. People tend to imagine that a fire burns on the ground or in a corner of the house and stays there for a while, but it can spread through the roof and walls, so don't grab anything and run!
5. Lost and without water
If you are lost and without water for more than two days and have to choose between drinking untreated water or not drinking at all, drink it. If you don't, you will die of dehydration very soon, and the illnesses you can get from drinking dirty water take a few days to develop, giving you enough time to seek help.
6. If you are trapped in the high tide
If you are trapped in the high tide, swim parallel to the shore until you are out of it. Swimming directly back to shore will get you nowhere and will exhaust you, which is extremely dangerous.
7. If you are choking
You can perform the Heimlich maneuver on yourself when you are choking and there are no people nearby. Press your fist against your abdomen and lift. You should press your fist and your other hand against the diaphragm or stomach area. Add force with a stable object, such as a chair. Repeat the process until the obstruction is cleared.
8. If you see someone fall on the ice
If you see someone fall on the ice (river or lake), lie down on the ice and crawl towards the person. DO NOT walk on the ice. By lying down, you reduce the likelihood of falling as well, and therefore both of you would be in the same situation.
9. How to identify a stroke?
Quickly, look at the face, arms, conversation; time is of the essence. If the person has an uneven smile or part of their face is "drooping," if they raise their arms and one of them falls or they can't raise them high enough, if their speech is slurred or unintelligible, ACT QUICKLY! Call an ambulance immediately.
10. If you are stabbed
