As an actor, the biggest compliment you can get, in my book is for someone to believe that you're the character.
I try to make myself walk around a bit, but I probably think about it more than I actually do it. Years ago, I did think about joining a gym.
A friend of mine described it this way: When they were born it was like a meteor landed in our house and blew everything apart. We had to just put all the pieces back.
