How to exit

I hear so much about people being stricken by dementia and/or Alzheimer’s, and forgetting who their loves ones are; I really hope that I can avoid being a burden to anyone around who still cares about m e, if those diseases are my fate.

I think the ideal way to go would be line Eduardo/El Macho in Despicable Me 2, who rides a shark strapped with explosives into a live volcano. 

Ah, but who knows. Will I know what’s going on it time to take control? Will I slide blithely into oblivion? Will my loved ones be so grief-stricken that my exit in a hospice bed in the front room would be easier on them? (Is it presumptuous of me to assume there will be anyone around who will give a rat’s ass?) Is it selfish to want to just ride a shark into a volcano, when one is terminally ill?
