I don't eat much meat and almost no beef. The last time I had a burger, about 10 years ago, I felt sick. I eat fish and especially love milk products ever since my first day here. I do eat plenty of veggies. Lest anyone mistakenly think I've spent a lifetime taking care of my
health, I have not. Mostly i'm the fortunate recipient of good genes from long lived ancestors. I've gotten smarter as I've gotten older and nowadays pay much more attention to diet. The relatively few aches of age, I deal with by stretching daily to preserve mobility and exercise to maintain strength. For instance, a somewhat troublesome knee, when it acts up, I deal with by knee exercises with ankle weights and a troublesome back, with core exercises. Medical researchers are now recommending weight training even for oldsters as a way to maintain quality of life.
