“ ...studies show that in general, optimists die ten years earlier than pessimists.I find that hard to believeOf course you do, you're an optimist. You have a misguided belief that things will go your way. You don't see the dangers till it's too late. Pessimists are more realistic. That seems like a sad way to govern your life.It's a safe way to govern your life. ”
