A lot of manual labor jobs result in destroying your body. Joints, backs, hearing, etc… it all goes much quicker when you’re lifting all day long and/or in a factory.
do those people imagine you are stron man when your back gives out at the age of 30?
I'd say the people who benefit the most of someone's back giving out at the age of 30 are very happy that there are plenty of willing people that want to be seen as "strong".
