I did an experiment a couple of years ago without knowing it. So if I didn't know about it, can it be called an experiment?

We moved to our weekend home full time when the Pandemic lockdown started. It's in a rural area, and our road is quiet and lightly traveled. So every morning, I would go outside wearing very little or nothing at all and stand outside for just a few seconds so I could experience the clean, cold air. My feet were bare.

As a result, my feet tolerate cold temperatures much better now. I often go out in the winter wearing sandals with socks. Sometimes my feet even get wet, and it still doesn't bother me. It's weird, but I'm happy about it.

I wish I could do the same with my hands. My hands still get painfully cold easily.
