Hold tight as a skydiving accident slips you out of your parachute harness as you plummet back to Earth from 13,000 feet. What would you do: get to your partner's ripcord, spread your arms like an eagle or grab your shins and hang on for a wild ride? In the next scenario, try to rescue a man after a motorcycle accident pins him under a burning car. And engage in arm-to-arm combat with an angry octopus that has one of its powerful tentacles wrapped around your only source of air.
