I hope he watches it. I was very thin and fairly well built until I reached 35, and I started gaining. I looked a little like he does for several years, and then it went crazy. Now, I weigh over 100 pounds more than I did then. I used to wear Speedos. I couldn't even get one over my thighs now much less up where it belongs.
Just a warning, it gets harder and harder to stay trim as you grow older, and if you stop, just for awhile, the fat jumps on you.
Also, as Oprah's favorite doctor said on her show one day, every thirty pounds a man gains causes him to lose one inch in his visible penis. If I gain much more, my penis will disappear....
