I'm 63. In my head maybe around 30 or 40? Hard to say exactly, but way younger than I actually am. I still feel daft and still like to have fun and mess about like I did when I was younger. When I WAS young I never imagined that when I was this age I would still want to act silly sometimes and giggle, and still enjoy "young" things. When I do things with my 35 year old daughter we often seem to act like daft teenagers. But my body betrays me a lot - I have a bad back and I get tired, and there are some times when I DO feel quite old, but it's physical stuff, not a mental state. In my head I remember very well how it felt to be 30, and even 16. And I still feel like that in my head, much of the time. People often tell me I look much younger than my years, so I try to live up to it in my attitudes.
