Trump's father made it to 93.... Now Trump is carrying at least an extra 50 lbs, probably 70. That is not easy on the heart.
To live long, you have to be slim. Look at this 110 y/o Indian Man who lived in the cave. And he can still walk (but slowly)! In fact, by 50 y/o, you can see many 'healthy' man moving around in a Motorised wheelchair!!!
According to his former campaign manager Trump will often skip breakfast and lunch; how often is not specified. The food he eats is truly awful.
