Only 2 to 3 degrees of separation between perfect temperature and too hot?
That’s really sensitive. I’d say most people can only feel 5 degree differences. Plus the fact you get acclimated to temperatures too.
AC at 16 for now! It probably does 21 or something, but still standing half-naked in front of it after hiking a few miles in 35 degree (more in the sun) is just heavenly!
My apologies to nature and earth! (Although I assume the electricicity is produced with photovoltaic cells)
