Super glued together a big cut on the bottom of my foot while at the beach.. End of problem, healed perfectly...
I was going to just cut the rest of it off...My pop said...nope, just place that piece on the stump, and tape it on...it will grow back.
I thought he was nuts...but it worked.
Broke my hand years later...sliding into second base. I knew where I broke it...and how it was broke. People told me..."Oh you have to go the doctor...!!" I didn't go...it never hurt, and I knew they couldn't cast it. And lo and behold...it healed.
