Great idea, there is so much doom mongering. I'm 5' 7" and 140 lbs. That puts my BMI in the middle of the green band so I'm very happy with it. I don't really diet, just take care what I eat and it helps that I like fruit and vegetables. Last year I started regular exercise and I do 25 minutes every morning. I thought people my age were supposed to talk to their doctor before taking up exercise but I didn't bother. I'm 64 and I'm just starting to learn about flirting.
