Ralph is going to live to an impossibly old age. He's going to be like Ozzy Osbourne or Keith Richards where somehow the amount of drugs and booze and plain beef he consumes is so vast that by some unknown process it actually preserves him like a living mummy. I would joke when I had the coof that I had to daydrink every day because it would kill the coronavirus (I was actually just bored and you can order delivery from liquor stores now) but Ralph is actually drinking enough that his blood is basically hand sanitizer. This is how he's able to eat shit out of a woman's ass, he has become something that isn't quite human anymore so diseases that can kill people don't know what to make of his highly exotic body chemistry. Any virus or bacteria in Ralph's body is like a sperm cell that was busted into someone's mouth or ass, just totally confused.
