Yeah, saw it on Pharyngula as well. I think don't think the intent was for people to take it all that seriously.
And re the comment from Sirdrinkalot, who probably should avoid posting in this thread, if you know what I mean, he's probably closer to the truth. Sugar is sweet because it tastes good, not the other way around. (and it tastes good because it is a high energy food)
I'll throw it out there and say that the taste of the subject matter of this thread is not selected for. But drinking things with a similar taste or texture probably is selected for.
Hmm, next time I get into a pissing contest with one of those kangen water people, I'm going to throw this in their face. If drinking their alkaline water is so great, how come semen tastes so bad? Or are they suggesting it would be healthy for people to do more of that? Maybe I'll bring my wife with me when I have this conversation.
