I agree with you that the caveman parable is silly but you are also drawing a false conclusion. It probably wasn't a caveman's diet that caused him to die young.
You're right, but the 'eat like a caveman to stay healthy like a caveman' is exactly what paleo-proponents use for argument.
What I meant was that you can't draw any 1:1 conclusions to the diet-to-health relation of cavemen compared to our diet-health relation. As always, people find it hard to understand that correlation is not the same as causation.
