in the deancas post canon that lives in my heart where cas is back from the empty and mostly human with a finite amount of grace (more than he could have hoped for!) cas is constantly experiencing a trolley problem of how to spend himself. what hurts merit his involvement? what illnesses? what if he uses too much on something human medicine could fix and then something beyond medical intervention happens later and he doesn’t have enough? when he runs out he doesn’t THINK he’ll die but he knows now that his death will kill dean. so he has to take care of himself, too. and dean has been developing the worst health practices a man can live through for the last 40 years and it’s miserable to rewrite all those bad habits into something that will give them enough time together. and if cas tries to earnestly lecture him about eating healthier or being more careful or, god forbid, doing daily stretches, it will start a fight that lasts anywhere from 5 hours to 5 weeks, which—again—is not time he wants to waste that way. so what i’m saying is cas is going to figure out fast how to turn the maintenance of dean winchester’s health into a sex thing to get him on board.
