I was thinking today - what if being upright wasn't particularly good for us? Does doing handstands often give a more even body balance? Maybe standing on your head does wonders for your insides, loosening up old dirt and grime and shaking it to the floor. I am no weirdo, and I'm not about to embark on a lifelong diet of wood chips, fish scales, essence of lizard, and making sure I only breath the finest filtered air available through a severed elephant trunk to further my existence by a few months (which would be a much more miserable one by then! Damn lizard essence) - but I am curious and like to ponder things in depth.
So I was thinking, what percentage of your life would you be upside down? (We'll cast aside sleeping as that is horizontal, and you probably do a fair bit of innard mixing in that position anyway.) Would it be half your life, to ensure a decent mix? if so how would choose your switch over times? Would it be one week walking on your head, one week on your legs? Or would it be the slightly hilarious but more efficient 5 second switcharoo? Personally I think a short time of a few seconds would be excellent - giving not only a good mix but also building fitness and reducing obesity. Also there would be added bonuses of a feeling of unification amongst people, that adds to the community feel; amusement wherever you look (at the different techniques and odd situations); increase you acrobatic skill and flexibility.
I think this is a truly excellent idea. You may be thinking 'Golly that sounds awfully difficult Faraday!' (That's if you have an imaginary friend inside your brain named Faraday) - but I mean really, everything is hard until you can do it right? I think you're just lazy and don't want to learn. Learning sucks you say? Well, prepare to fail in life. Take that.
