Today, I thought of a practical value for space - I mean outer space!
I was watching this video
where an astrophysicist explains gravity and she mentioned that astronauts actually get taller in space because gravity is not always scrunching their spines.
We all have neck and back problems, right?
Well, what if you could pay someone to put you into anti-gravity for several weeks in order to release all the tension in your neck, back and muscles? It would be a fitness routine in anti-gravity. An anti-grav gym! Think of it! Go into a special fitness spaceship and get your exercise routines, health-diet, massage therapy and chiropractic for two or three weeks straight.
A fitness-space cruise!
Yeah it would be expensive, but after time things could calm down to a normal consumer level like other gyms.
This would make space to actually have practical value for practical people. It would pave the way for colonizing the moon - think of the trails we could build on the moon - what kind of exercise would you get for your moon-mountain bike! The commerce that would be caused in the fitness-space cruise would make it more sustainable for colonizing the moon. Wouldn't a moon-based campus be more practical and spatious than being cooped up in a teeny modular spaceship?
But really, the space-fitness stuff could be carried out still in close orbit and wouldn't require the resources of a full-fledged spaceship, for now. All we need for that is an good-sized anti-gravity chamber.
