I'm missing part of a fingertip. I'd like to try this "pixie dust." I work with a guy missing an entire finger, but since this material can't grow bone, I guess he's SOL.
I vote we take a liberal- Nancy Pelosi would work fine- amputate her arm, and see if this stuff allows it to grow back. It's for the children, you see!
Fingertips HAVE regenerated in the past, but that's generally in people under 25. That it happened to a man this old is quite remarkable.
