I love swimming. I enjoy it for recreation, and it's one of my favorite sports to watch, especially in the Olympics.
I don't necessarily like watching it but love swimming myself 
Olympic-sized pools, while the standardized size, are huge compared to the backyard ones I'm familiar with.
I have been swimming in a couple Olympic sized pools. They are massive and seem even bigger when you're in them. 
It's interesting how historically relevant swimming pool-type facilities are. Mostly talking about the wading pools/public baths of ancient times.
I find them confusing. I suppose they were set up like that because a lack of indoor water for houses then right?
I think so. With limited infrastructure, public baths allowed for community-wide access which helped with hygiene and whatnot.
The way they are portrayed is like they were somewhat of a social gathering at times too
Public bathing were more like spas of today, with saunas and massages. Really provided community services to those it was available to. 
I get that. I suppose the thing that gets me is being naked around so many people
