I'm still young

So I'm 41, 5'7" and 160 lbs, an alcoholic and barely gets time to eat and sleep cause of work. Today i picked up 150, 80lb bags of concrete which equals 12,000 lbs. Smallest guy on the crew. This after shoveling thousand of lbs of chipped concrete into a wheelbarrow rolled that up 2 semi steep ramps and dumped it. Then I'm told I'm weak. Ok. I forgot my balls it seems. BTW. This ain't a pity party n if you try that, then FUCK OFF!
