That's what CBC Radio's WireTap asked a group of people from age seven to 93. Obviously, they all had very different things to say — from "Find out your babysitter's weakness, then use it against them" to "Don't listen to other people's advice" — but all equally valuable.
"How To Age Gracefully," directed by Andrew Norton, shows us that growing up is a never-ending process. There's always something new to learn — even in your 90s.
Moral of the story? Stay weird. Do your own thing. And seriously, don't let your mom throw away your LEGOs.
