That's 420 pounds.
I used to work in a factory with a guy that weighted over 400 lbs and he had to climb a ladder every day to get to his work station. The ladder was quite steep and to watch him come down it was quite an event. We had bets on what would happen if he ever fell off but he worked there about 25 years and never slipped once, although he could not see his feet while climbing down.
That’s Lard On.
