This sort of stuff has been something I’ve been getting into. I wear minimal shoes (on the rare day where I actually need to wear shoes. wtf is up with people who wear shoes in their house ew) but things like sleeping on the floor just do not work for me. Tried it for a few months, even invested into a proper floor futon, and the only thing I experienced was a profound and unending discomfort. I must just have worse bone-itis than Fry’s 80s guy friend. Or maybe all the “return to monke” stuff is bullshit, and we’re as big of dopes as the paleo diet freaks.
