Yes sitting will kill you, but what are you doing while your sitting. If you snack while you sitting your in trouble. Over weight is a gland problem. The gland is your mouth gland the more you put in it the bigger you get. At my old age the best thing is to STOP all snacking and no pastry at the meals. I didn,t see a doctor for over 40 years and now have all of the old age problems. I have never smoked but have gout from eating rich foods at Mc Donalds. I have stopped snacking after dinner , no icecream or sweats, and have lost about 12 lbs and thats a start. I hope to be 70 next year and have to take care of whats left of me and make the parts last. jz.
