YouTube suggested an old NileRed video to me today. He bought 100 lbs of titanium shot for a project. It came in a bag in a metal can.

The first two times he lifted the bag he said this isn’t that heavy, maybe he got defrauded, so he got a scale and checked. But by the time he tried to lift it off the scale he was struggling, and getting it back into the metal can was serious work.

Stamina separates the pro from the amateur, but fatigue comes for all of us.
