Better way to put it thanks. We didnt live longer, true, but life was also much harder on the body. Altho now, while we dont have to work as hard, we destroy ourselves versus letting nature do it for us. I always wonder about allergies and stuff. Did our ancestors suffer like people today do? Or were they immune because so much more of their foodstuff was from the land around them versus freezer packaged/bought, etc...
