AAAHGH GET THEE BEHIND ME SATAN
I suddenly feel a compulsive need to write a thinly-disguised knock-off of Heinlein's "I Will Fear No Evil" about a dying billionaire who has his brain transplanted into his (brain-dead after a car crash) secretary's body (he's dying from the same car crash), only to find that she's still aware in there, they're sharing the body, and she hates him. (Think Trump getting himself transplanted into Ivanka.)
No political satire intended, honest.
