I actually rub my chin nowadays and if the hair is starting to grow too long there on the face I figure it must be time to get cleaned up. Of course, if I have urgent matters to deal with I will shower first. I also wear clean underwear and clothes and will wash the hands and face, even do a facile sponge bath if it gets rank, I do not want to smell, ya know. But it seems kind of futile to be overly sensitive about getting all washed up when I am already all washed up and gonna die right away anyway, OOOPs there's that damned C-PTSD again
