“Growing old is no more than a bad habit which a busy person has no time to form.”

“To my mind it’s curiosity that’s the key to longevity. As long as you’re curious about what’s behind the door, you’ll always open it. And the more doors open, the more places you go, the more things you see. You don’t get smarter as you get older, you get braver.”

“In the end, it’s not going to matter how many breaths you took, but how many moments took your breath away.”

“You know you’re getting old when you stoop to tie your shoelaces and wonder what else you could do while you’re down there.”

“I intend to live forever. So far, so good.”

“Some people are old when they’re 18 and some people are young when they’re 90. You can’t define people by whatever society determines as their age. Time is a concept that human beings created.”
