How does he fit all his camping stuff in his one bag? This was not explained. He "tosses it in his bag" for outdoor trips but tossed from where? I thought everything he owned was already in his bag.

How does he "not buy stuff frequently" if he discards & buys new swim suits (and presumably other stuff) as needed?

Sounds like this guy has a pretty cool & minimal lifestyle but I suspect there's some exaggeration and elision going on in this post.
