If I had dementia the question of whether I would end my life would become irrelevent. This thread is about rational suicide.

Dementia may just sneak up on a person who had always decided before diagnosis of dementia, when enough was enough, they would choose rational suicide. In the end though they may not taken that choice soon enough and will spend years in a secure unit in a retirement home.

I speak of pain in many facets not just physical or psychological, e.g. pain of losing your dignity, your mind....etc etc

Again, those people are usually suffering from dementia ( can strike a  60yo, early 70's, 90's anyones guess what age some people will get it) -'will suffer loss of mind, loosing their dignity.

How would an older person ensure they were gone from the world before dementia snuck up on them?
