When was the last time you met somebody who only walked all thier life? Never rode a horse because only the rich could afford such things.
When was the last time you had no food? Starvation used to be a real problem. I'm not taking about running short at the end of the month, I'm talking about there isn't food for even the wealthy people.
Food today is safer than ever. You talk about poison, but that is pure lie, it might not be the best, but it isn't moldy because you have a fridge.
