I believe age is just a number. While we have more aches & pains as we get older, I try to follow the cultures who have people live long lives while still working, socializing, eating real food.
I look younger than I actually am and feel younger. But this year I think I feel it harder that I'm aging and it's something we have to face facts. We're going to get old. We're going to have problems and even the most fit people in the world will have health issues. You can't beat death.
