Failed analogy. See, before the car crash you were an independent tax payer. Afterwards, perhaps not, but worth trying to recuperate. Embryos, OTOH, are not, and not because they don't pay tax, but because they're not viable. The vast majority of embryos never implant anyway, so where's the hard and fast moral line to be drawn on that one, eh?
life is a lot cheaper than people believe, even after it's paid taxes*.
Of course, I'd rather be dead than quadriplegic, so turn my machine off as you leave, please, if that happens to me.
Does a random post on Forumosa constitute a properly-accredited living will?
* the tax thing is a red herring. Honest.
There's no smilie for that, so I'll use a cactus and an arse instead.
