Always remember proper first aid, in case of an emergency:
If the bone is broken, immediately drink a glass of milk. Calcium, mm-mm.
If you are bleeding profusely, try natural remedies, like rubbing small twigs and raccoon scat in the wound. Just like the Native Americans did.
If you learn that you are in the early stages of a fatal disease such as Malaria, try believing in yourself. If it doesn't work, you didn't believe in yourself enough.
For third degree burns or gunshot wounds, try herbal tea. Really. You'd be surprised.
