1. I would like more buoyancy, in general. No real interest in flying, but I think it would be great if we could really rebound out of movement and get some gravity defying air time in the process.
2. What if some sort of activation color, light, or button appeared on you when your body was doing major work on it's own, like fighting a disease, reproducing cells, regenerating tissue, or creating a baby? That would be cool.
