I love saunas.
It's where I go to relax.
It's where I go to brainstorm and ideate.
It's also a great place to meet people and chat. When you're semi/totally naked, people are much more willing to converse.
The other day, I met a therapist, a retired Psychology professor who had just become a minister, two Korean men who told me about WWII and the Japanese, and a guy from El Salvador whom I may end up hiring to paint my house.
The NFO once told me that it would be a mistake to have a sauna in my house (this was pre-economic meltdown..and it wasn't ever an option then anyway), because I'd lose the social aspect. She was right.
