Forgot that one. I experience the same. I am the only person on my mother's side of the family who has not had back surgery (in most instances, multiple surgeries) and dairy certainly exacerbates the problems I do have. I know part of the problem is genetic, but a large part of it is undoubtedly attributable to carrying around large backpacks for days, weeks, months on end throughout a good portion of the past twenty-plus years. Those were the items that I suffered least from, as well. And while I can eat corn, corn chips, etc., anything with corn syrup--which sadly compromises the bulk of many Americans' diets--seems to take a toll on me. There are those who "argue" that it's too expensive to eat well. One here, a moderator no less, posted a link to an article which purported to argue his case. Had he actually read the article, he would have noted that it stated precisely the opposite: it is significantly cheaper to subsist on proper foods.
