If it's still not clear:
1. I didn't like him using survival as proof of healthiness so I mentioned that we don't know how well did people live back there (and if it was related to their diet), that was still about paleolithic
2. I didn't like both of you using infant mortality as proof of healthiness but I couldn't find any reliable data about paleolithic so I mentioned neolithic life expectancy. It was not related to the original topic anymore.
Why am I so bad at this?..
