Supposedly, Jett Blakk's "Endgame" (recently released) was his LAST porn film before retiring from the biz... and to "prove" it, he bottomed in the final scene... which was okay, tho I wouldn't want to go out being the bottom in a gang rape scene for my finale...
He's still fit & looks good on camera (tho a decent haircut would do wonders!)
Not sure if he'll pull a "Cher" deal, & stage untold number of comebacks.
Regardless, there are a lot of hotties in porn that work WELL into their 40s... (LOVE the salt-n-pepper look!).
But whatever... he's got a fairly substantial body of work, whether he does any more porn or not. Just hope he's happy.
