Here’s how you could look in your late 60s & 70s; with a bit of attention, especially good animal protein intake, resistance training, and if need be (as in the case of Dr. Life) some bioidentical testosterone and HgH ($$$: Scott Miller: what does it cost?).
You could look like Art, at 72. He’ll tell you himself: I’t’s not hard.
How about Clarence Bass, at 70?
Then there’s Dr.Dr.. Jeff Life. I have two pics, the first one that Beatrice & I saw on a billboard in Vegas a night or so ago.
Here he was a few years back, winning a Body For Life Comp, I think.
Or, you can look like these assholes, Dr. T. Colin Campbell and Dr. Caldwell Esselstyn: old human skeletons so un-virile (impotent, yet?), so unappealing. They want you to eat — because they do and misery loves company — a pea-brain (literally) diet of hominids that’s obsolete for humans by about 4 million years.
I can accept that this sort of monkey-wrenching diet could work for some people already far gone (but Paleo would probably work better — just get off processed foods), but that’s only because it’s pharmacological in scope.
