“Back in the day” it was a given that hard work was going to be done day in and day out.
Hard physical labor was a way of life.
Today, few people know what hard physical work is like. It was often dangerous work, too.
I recently saw a photo from my buddy Don Giafardino, that is similar to this old photo. He was up on a crane doing real work, all day every day. He understands work capacity is in the real world.
I remember my Italian Dad getting me a job as a “mud-tender” when I was about 15 years old. I pushed wheel barrows of wet cement to keep the block masons supplied so the could keep laying block all day.
Our troops still know what hard work is all about, like this soldier.
It doesn’t matter what you can do in 15 minutes in the real world.
What can you do for 8 to 12 hours day after day?
Don’t fool yourself about how fit and strong you are based on the gym alone.
