Fahrenheit isn’t how people feel, otherwise 50° would be perfect temperature.

it is though? It's like perfectly comfortable because you can dress up just enough to where you're actually wearing a decent bit of clothing, but you can also dress down to a pretty light set of clothing as well.

This is also ignoring that this is both, arbitrary, and also completely subjective to the person.

The human body might end up liking 70f more than 50f, purely because it's 96f inside the body, so something lower to allow heat transfer, but not low enough to be physically uncomfortable would be more expected.

Actually, here's a good question, why do you land on the 50f point? Are you expecting the middle to be the most optimal point of perfection? Or is this just a metric brain thing?
