I was about to write an exciting article about the psychological component of effort based on my experience with the rowing machine at the gym: some days, It's a breeze; other days, on the same machine set at the same level, it feels like it weighs a ton.

I was going to explore in detail the psychological, neurological, and physiological origins of this discrepancy, and everyone would have found my article funny, well-researched, and so well-written.

Except that this morning, I discovered the truth.

When I lay my towel on the roller, the fabric prevents the moving air from escaping, and the suction maintains the rotation – or something like that – so that the exercise becomes much, much easier. But as soon as I place my towel elsewhere... Welcome to the Roman galleys.

All of this to say that the laws of physics have spared you another stupid article.

Thank you, science.
