Hey, Mad Asshatter here. I was Maggot, but an expired burner email and a half remembered password meant I had to reregister.
Anyway, if Big Al thinks she is going to to go well into that sweet Kentucky night, she's dreamin.'
A couple of older 400 pounders that I knew (not even Big Al's size) ended up living life out of a Lazyboy chair. Both had secere mobility issues, both were incontinent (which made their houses smell like pee) and at least one that I knew of had diabetes.
She's not going to drop dead at 40, she's going to liiiiinger and her life will increasingly get more and more isolated, boring, and pain-filled until dying a gasping, breathless heart failure death, at 40. If she get's diabetes (and if the black knucks are truly a symptom) then she's going to eventually have to take insulin and watch what she eats, or she faces the dangers of very high blood sugar, high risk of amputation, stroke, blindness, or a heart attack, which either kills her outright or leaves her feeling a constant sense of dread for the next one.
It sounds cruel, but eventually she's going to become a white elephant if/when that Youtoob money dries up, and all Becky and co. are left with is an immobile, demanding narcissistic 600 plus pound person that no longer contributes to the household expenses, now has a shit-ton of expensive medical issues, and because of her size, is very, very VERY expensive to feed. People can overlook a lot of expensive and care-taking issues when it's someone they deeply care about, but Becky only seems to play-act at love nowadays, so I could see Big Al getting stuffed in a state-run nursing home when Becky finds another girlfriend (or decides to move back home to be with her Ma.)
