Alzheimer's isn't like being dead though. It's an incredibly painful reminder to everyone you've every loved that you are no longer "you", but they have to take care of you every day anyways. Painfully re-opening wounds every time you don't remember who they are, or hurt yourself from confusion. It's a continuous living purgatory for your loved ones, with you gone but not gone.

I'd rather live the best, unhealthiest life, and hope I'm dead dead from other causes before I can cause so much pain to the ones I love.
