I just renewed my CPR / AED certification.  

They say that MEN, when they start to feel BAD (as in a heart attack), walk away from people.  They prefer to die alone.  For example, if they are having dinner at a restaurant, when they start to feel a heart attack, they will rush to the bathroom.  Therefore, there is no chance to do CPR on them.

Watch out for someone rushing to go to the bathroom.
