A really good one... doesn't matter. I need to get my tickets back for the allman brothers concert... I'm going to get shrooms for it.
average american spends more money in the last 6 mos of life on healthcare than in the rest of their life combined (I said average) usually this does little or nothing to improve quality of life, from a cost/benefit point of view euthanasia is a viable option, but you have to ask how valuable is that hypothetical six months to that person.....
