I may not have the endurance to run to the store, but construction is not for the timid, weak or know it alls. Besides, if you go to the gym, you gotta keep going, otherwise all that crap comes back on ya. I aint got that kind of commitment. Construction offers me enough balance to keep me in shape, the shape I need to lift heavy shit and wield heavy tools. The guys I work with in their 30's n 40's are a f**k load tougher than the 20 "is it break time yet" year olds. We got this shit, let's have a beer bud.
