Increase your chances of escaping dangerous quicksand, being buried alive, deadly bear attacks, and more.
How to escape quicksand
Quicksand, formed when sand becomes so soaked with water that it can no longer support weight, can be dangerous. Some movies have led you to believe how deadly it is to meet with quicksand, but an encounter with quicksand doesn’t mean certain doom. Your body is less dense than the quicksand so it’s nearly impossible to completely sink (or be sucked under) if you stay calm. To escape, slowly pull each leg to the surface. Once you’re horizontal, either on your stomach or on your back, you’ll float better and be able to wriggle(蜿蜒行进) your way to solid ground.
What to do if you’re buried alive
Modern embalming (防腐) procedure and the amount of pressure created by tons of dirt on top of the casket(棺材) make the possibility of waking up six feet under nearly impossible. Still, it happens, so it’s good to be prepared.
