Occasionally Snarky and Meta

Fair enough - none of that was particularly directed at you, I just tend to overreact when I see people making accepting noises about stuff on the basis of science when the actual science backs up said stuff in no way whatsoever. (I would be prepared to accept behavioural changes on the basis of light levels, say, because that's a direct, measurable effect with several possible mechanisms; it's just the gravity stuff that makes me go gah.)
