I dont like this look on him, to be honest.
Dude's nearing 70 with a history of heart problems, surgery, etc.
His body got smaller over 2 decades, as it was meant to be. Not saying he turned into a fat slob, but when you're 55, 58, 62, 64 and you have ticker issues, being lean and light is 100% the way to go. The heart can't tell if it's 230 pounds of muscle or 230 pounds of fat. It prefers 180 much more.
I think this muscle gain is ego-driven (who can blame the dude!?) but he should not keep that large for long. It's a big shock to the system of a dude that got small for over a decade.
