Then I finally couldn't stand it no more and took them off. Then I tried switching one pinky to south and leave the other pinky north. Then I felt rejuvenation. I further perfected by adding magnets at bottom of pinkies, and felt more thorough rejuvenation. The rest of the fingers didn't work, and were not even close the the effect I got from the pinkies.
Pinkies are the most sensitive finger.
Between the invention of pinky rings and the foot braces, I tried nearly everything I can think of. Tesla coil, inducing wires on my body using high voltage, low amps. Nothing worked as good as a pair of rings on the pinkies. Except the foot braces. The foot braces worked, and worked better than the pinky rings.
