A thousand years ago, chronic back pain was likely unheard of.  Some basic research will tell you that Chinese and Greek medicine - and probably every other tradition of medicine - addressed lower back pain.  It still is unheard of, in some undeveloped countries where people actually exercise their ass muscles and don't wear gimmicky shoes  This statement too is false Rates are 2-4 times higher among Swedish, German, and Belgium general populations than among Nigerian, southern Chinese, Indonesian, and Filipino farmers. Far from 'unheard of'. The fight against FA idiocy has facts on our side. The truth is enough.  We do not have to peddle bullshit nonsense. That is their game. You're spouting feelings among your facts.  The fact is most people (80%) will experience lower back pain at some point regardless of weight. It's enough to say that fat makes it more likely and worse.
