COMMENTS: Unintelligent Spine Design
Got an aching back? Blame evolution, suggested Robert Bazell as he kicked off NBC's Back Story series. He crawled around a barnyard with pigs to illustrate skeletal anatomy. Backs "are designed for creatures with four legs." Stand upright like a human being and the shock absorber disks between the vertebrae are subjected to stress and strain that evolution has not prepared us for. Bazell argued that it has only been in the last 300 years or so that humans have expected to live past 45. So babyboomers with aching backs are suffering the consequences of living beyond their disks' due date.
