I think we should all know some first aid, it would be helpful to. You never know when it will come in handy.

Fishhook in Skin
Force the tip of the fishook out of the skin. Then cut the tip of the fishook off, and bring it back out of the skin. Apply soap and warm water and wrap with a bandage.
Hyperventiliation
First of all, hyperventiliation is a lack of carbon dioxide in the blood caused by breathing too fast. You want to try to calm the person down, lower their breath rate, and if possible have them breate into a paper bag. I think, but am not sure, repeated cases of hyperventiliation will lead to asthma. Does anyone know if this is true or not?
Hypothermia
Plain and simple: Get them warm. Give them warm drinks, but never hot! There is nothing worse than going directly from cold to hot. Remove wet clothing, get them a sleeping bag, anything you can do to warm them up.
Puncture
Encourage the wound to bleed! Yes, you heard me right. Of course, this is for a small puncture. Wash with soap and warm water.
More to come!
