And, you know, not to be all Debbie Downer, but there ARE real health implications from all that running. I can't tell you how many hip replacements I've seen in the course of my job on runners only in their 40s. If you've ever seen a fairly young person trying to walk with a new hip replacement, it is at best sobering .... at worst, alarming. Hopefully, the absence of grains and other inflammatory agents and running barefoot will lessen the wear and tear for the runners here.
