He has always eaten kinda low carb and gravitated to the paleo stuff easily.
I have folks in their 50's who are far off his fitness...it's just a crap shoot.
I'll second that. I've got a lady that just turned 70 in May (5'2", ~120). We've been working for the last 4 or 5 years to stave off a hip replacement that her doctor told her was iminent. She has problems with extreme ranges of motion, but we've almost got her doing an unassisted pullup, DLs BW+20 lb pretty easily (*if we start her 2" off the floor), and generally shows up some of my 50-ish clients.
She's been pretty active her whole life: horses and dogs, hunting, etc., and very into cooking. Kind of takes the French approach--all things in moderation. I generally pray I'm doing as well at 70.
