    Hi Joe, thanks also for the feedback. Fair enough, natural selection seems
    to favor the sober animal and permits the occasional user. So much
    for the animal kingdom, I'm still left with humans who, I think it's
    safe to say, generally are susceptible to develop addiction of whatever kind.
    Can you account for this with arguments ignoring human culture?
