[basisword]

I think it depends on how 'easy' it is. If it was as simple as pushing a button and you knew it was instant and painless I can imagine many times in my life I would have pressed that button - and I'm sure a lot of people might do it in moments of great distress, when thoughts of the future aren't there. I think the issue isn't the "know how" as you mentioned, it's more the difficulty and uncertainty (of pain and success). Working in a place that has the tools and you know how to use them reduces so many barriers to entry so to speak.
