Like Dancing on the Moon

In my house we love to listen to Stephen Fry. He could basically narrate the phone book (do people still know what those are? It's that big squodgy book full of advertisements that they leave on your doorstep wrapped in a plastic bag. You know the ones. The ones you deposit directly in the recycle bin without even glancing at) and we would listen to it in the car. Anyway. So my husband tracked down a silly little show he hosted a few year ago that featured gadgets and gizmos (aplenty. That song is SO STUCK IN MY HEAD.) and we've been watching it here and there.
Tonight's episode showcased this crazy thing:

it's an "anti-gravity" treadmill. It basically seals your lower body in a big plastic box with increased air pressure, which supports your weight so you "float" up and barely touch the track under your feet. They say it reduces the load on your legs to 20% your normal weight, the equivalent of walking on the moon.
It certainly has all sorts of wonderful uses in physical therapy. I mean... that is surely what it's intended purpose is. I should probably be thinking to myself "wow, that would be an amazing way to work out without causing my knees so much pain and wear".
So, why is it that all I can think is "HOLY CRAP let me at that thing in a pair of pointe shoes"
