Do all your social media while upside-down and you'll have a TWEETER Inversion Table LOLZ
Gravity keeps us from floating away. But gravity only works in one direction. Every now and then it's good to let gravity pull you the other way as well. But wouldn't it be selfish to just reverse gravity and make everyone else float away? Yes, it would be.
Your only option is to rotate yourself, like with a table or something. Thank goodness there just happens to be one right here, designed to rotate you without making everyone else float into the sun. What good is relief from joint and back pain if you're the only person left on the planet?
