Pro bodybuilders lose on average 2'' in height by the time they are 45 (due to steroid abuse), natty bodybuilders don't seem to lose any height at all
Examples:Arnold 6'2'' now 6' tall, Lou Ferrigno 6'5'' now 6'2.5'', Branch Warren 5'7'' now 5'5'', etc. I'm still 5'7'' at 44 because I do natural bodybuilding
