'Don't worry about senility', my grandfather used to say.
As a comedian, I can walk out in front of 5000 people and not worry about a thing. Not a thing, believe me. But to stand up a face a camera and crew of maybe 15 guys and get up tight about it - to me that's weird.
Every success story has a parent who says, 'over my dead body.' Every success story has an old person who walks up to you and says, when you're acting the fool, 'you know I worry about you sometimes.'
