With a title like that I was expecting your usual satire.
I wonder if you'd get many takers, even assuming price wasn't an issue. It certainly wouldn't be for the agoraphobic. The issue with euthanasia from the perspective of someone healthy is the thought of choosing your time of death. Yet I'm guessing it would be different when you're facing the prospect of choosing a dignified death or a slow painful or undignified one.
I expect at least 50% of men would take this option, given the chance. (assuming price wasn't a limiting factor).
I can't think of a mate who'd turn it down, to be honest.
