You just like trolling..Read the book! They might have eaten bugs, lizards, and whatnot to stay alive when hunting was bad back in the day, but only when they couldn't bag something better. And as far as healthy vegans go, they might appear healthy at the moment but down the road they may wind up with one of the many disorders and health issues that just didn't exist back in the day..As for myself I've never seen many healthy vegans or at least healthy-looking ones, they look either bloated and overweight or look half-starved. An archeologist can look at two different skeletons from two different eras and tell without testing if they came from hunter-gatherer days or post agricultural times. the agri era skeletons will have weaker bone, and missing teeth, whereas the Paleo guy will have better bone structure and all their teeth intact. Like I already said it's a free country..If one want to eat weeds and soy crap go for it..Oh and by the way, I sometimes eat seaweed myself, it's not bad eating when prepared the right way.
