Conventional wisdom demands skepticism. Whether it\u2019s the official stance on high-fat diets (\u201cthey\u2019ll give you heart disease, don\u2019t work, or do work but not for long!\u201d), exercise (\u201cyou must jog at a moderate pace for an hour a day, four days a week!\u201d), organic food (\u201cit\u2019s nutritionally identical to conventionally-grown food!\u201d), or sun exposure (\u201cyou must always wear sunblock!\u201d), I always question conventional wisdom. And when it\u2019s lacking (as is often the case), I rightly skewer it.
