| numerous injuries to my hands and fingers, including cuts,
| scrapes, gouges, slices, bumps, bruises, shocks and other
| insults and attacks be they physical, chemical, biological or
| what not with the consequence of discoloration, blood flow,
| pain, swelling, itching or what not. And yet now, I can look at
| my hands and they look almost perfect. Surely the act that can
| return these wounds back to near perfection is as incredible as
| the act of bringing life about in the first place. The two seem
| to be outcomes of the same code, at least from where I stand.

| He has some astonishing vids up on YouTube.
