Very true, Sandy. Numerous medications that can be useful and even vital for some people with certain conditions — under supervision of a competent physician — are often useless or outright unhealthy for others. I hope I communicated that much in this article. And yes, alcohol is really, really bad for us. I've written before about how no amount of alcohol is healthy, though some of us (me included) choose to enjoy it anyway. We humans are often stupid, and quite frequently... human.
