My grandpa was born and raised in an industrial town that didn’t have access to pools or anything like that. He decided to learn to swim by reading a book and practicing in his living room. He would lay down on a bench or a seat and practice the motions. Every year, he’d go to a nearby town that did have a pool, and he’d sit for hours hearing how kids were taught to swim. He’d then go back to his living room and practice based on that.

So, how did he swim? Luckily, looking at him swim was something I could do with my own eyes. And just by the look of it, you’d never tell he learned on a bench.
