Why don't blind people skydive more often?
It scares the shit out of their dogs.
How does a blind skydiver know the ground is near?

Bone repair by electricityIn 1971, the first successful use of electricity to repair a bone fracture is reported by surgeons at the University of Pennsylvania. Electrical currents have been used to heal bone since the mid-1800s, and the effect of electrical stimulation on bone has been long studied and well documented.When human bone is bent or broken, it generates an electrical charge ("On the Piezoelectric Effect of Bone", Fukada and Yasuda, 1957). This low level electrical charge stimulates the body's internal repair mechanism.[Image: steps in a fractured bone healing] |
