Too many times, people take risks for no good reason.
Paramedics sometimes risk their own lives to save others.
Firefighters enter burning build ings to rescue people. We realize there are times people have to take risks. But too many times, people take risks for no good reason, for example, a person who balances on the railing of a balcony six stories high to impress his friends. You have to know when it's worth the risk. That's what separates the heroes from the fools.
