The question that needs to be asked is this:
Which one of those two would most possibly make it to 70? Who would you put your money on?
Branch working out around Arnold back in the day would have been akin to just another Ken Waller--maybe Platz or any of the other guys that never really "made it" to the big time.
None of those guys back then even came close to the big shredded, ripped and torn up physiques that we see today, and it sure as hell aint because of lack of dieting or working out hard.
May as well compare a Peterbilt to a Dodge Ram.
