SURVIVE A HEART ATTACK WHEN YOU'RE ALONE

Since heart attacks can happen at any time, you could be alone when one strikes. You can do the equivalent of CPR on yourself by doing very vigorous, repeated and prolonged coughing. Take a deep breath before each cough. You'll need to repeat the breath and cough every two seconds until help arrives or your heart returns to normal beating.

This is one tip I hope you never have to use, but if you do COUGH!
