Apart from all of your examples looking drawn and emaciated (which does not apply to Kovacs), I don't know what you are talking about. I am plenty old, probably older than you.
Anyway, it is not worth pursuing this. Greg Kovacs was a superstar when he was young. He had flaws like all of us, but he reached for his dream, which so many people never do. RIP.
If you don't see it, you don't see it. Obviously, you can't see what many others can. So be it. But is the arc of his life and career really something you are applauding or wish to emulate? I doubt it. Happy marriage? Children? Professional/financial success? Notable charitable work? Artistic legacy? No. No. No. No. No. Dead at 44 with virtually nothing to show for it.
True, he burned brightly for a short time but most of it was hype; his bodybuilding record was hardly distinguished.
