" ...studies show that in general, optimists die ten years earlier than pessimists."
"I find that hard to believe"
"Of 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. "
