I'm gonna be honest, I don't know what he CAN do. Even if he did everything perfectly healthy and correct from today on, he would still be a tweaked-out pedophile loser with shattered legs, heart problems, and no redeeming qualities. I hate to talk like I'm siding with boogie, I'm not, but I'm not sure it's even worth his nonexistent effort to better himself at this point. He's old.
I don't like to encourage this type of behavior or put it in his mind because I know he's gonna see this, but if he really is as shameless as he makes himself out to be, he should just indulge. Give away his dogs, donate/give away his gamer shit, and put together his remaining bucks to buy a week's worth of Marcos, hookers, and party hard. Maybe pay ONE hooker all the money and indulge in all his sick fetishes before he dies. this one scares me but he could even go all in and try to carry out his horrible pedophile urges and download a bunch of cheese pizza videos- I'm sure he has the connections- worst case scenario it would take at least a day for the feds to bust down his door or whatever. By that point he'd be dead
What I'm saying is: taking boogies interests into account realistically, his most fulfilling course of action would be to party himself to death for a few days and just be done with it all.
I can't even wishfully imagine any worthwhile positive outcome for him. His only options now are to go big or go home.
