You might wish to read up on art history: Sistine ceiling was finished by a 37yrs old (1512), Judgment was finished by a 66yrs old (1541). In his 70s he was painting the walls of the Capella Paolina - next door to the Sistine, but completely different. And it was Leonardo who was a homo, while Michelangelo was merely manic-depressive. Besides, with his personal hygiene [his father advised him never to wash] getting younger lovers must have been problematic, to say the least.
"...while Michelangelo was merely manic-depressive. Besides, with his personal hygiene [his father advised him never to wash].."
Not only was he depressed, but stinkin' depressed.
