Thank you for posting - I completely agree.
I wouldn't want to be hooked up to life support system in the future. Why burdening families with medical bills while I don't even have a quality life? When I die, the body can be donated for medical research and no memorial service necessary.
By the way, my best wish is to feed my body to fish after I die because I had eaten so many of them growing up in a fishing village. It would be a great natural way to pay back. :-)
