I got an email from a friend recently and i decided i will share with everyone. Teach this to your parents.

HOW TO SURVIVE A HEART ATTACK WHEN ALONE
Since many people are alone when they suffer a heart
attack, without help,the person whose heart is beating improperly
and who begins to feel faint, has only about 10 seconds
left before losing consciousness.

However,these victims can help themselves by coughing
repeatedly and very vigorously. A deep breath should be taken
before each cough, and the cough must be deep and prolonged,
as when producing sputum from deep inside the chest.

A breath and a cough must be repeated about every two
seconds without let-up until help arrives, or until the heart is
felt to be beating normally again.

Deep breaths get oxygen into the lungs and coughing
movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal
rhythm. In this way, heart attack victims can get to a
hospital. Tell as many other people as possible about this. It
could save their lives!!

A cardiologist says If everyone who gets this mail sends it
to 10 people, you can bet that we'll save at least one
life.
