It’s mental illness but not dementia. Alzheimer patients can’t maintain any kind of real goal — no persistent goal seeking.
I am well acquainted with Alzheimers and senility-but in both the people have delusions. Granny can think she’s 30 and a stripper again- so does she get surgery-free- to look hot and young again? Grandpa can think he’s Tyrone Power-is that good enough for plastic surgery? Why not? If medicine can make you what you THINK you are-and offers free mutilations rather than mental help-who decides a 70 year old can become a woman, and another can’t become, say, a Klingon? If it makes a senile granny happy-wait for it-complete makeover with implants and plastic surgery for FREE!
