Finally, somebody said this.

Throughout history, people have bathed in public rather than in private. Should we bring back the public bathhouse for the sake of sustainability?

I can hardly imagine myself using one daily. I'm late for work every day,having to go to a yet another place just to clean my meat case sounds ridiculous. Also, I wouldn't particularly enjoy bathing in public. And let's not forget about hygiene. Modern people barely manage using public toilets, and you expect them to manage something even more complex?

But energy-wise, communal bathing is indeed effective.
