Look, we're Americans: optimistic, addicted to the quick fix, constantly on the hunt for the new and exotic. It's much easier for us to accept a guy with a big white beard hawking his own custom blend of saw palmetto and squirrel dandruff that it is to hear a real doctor telling us to lay off the big macs, and get off our fat asses and take a walk every decade or so.
I study the bible regularly, meet with older wiser mentors weekly, and keep a group of guys in my life who challenge me spiritually. That keeps me moving.
