When We are scooting around in the Wild, We get revved up. Some sort of whiz-bang happens inside, which is called Endorphins. We feel great, very Can Do. Not so much nutso, as Dynamic and Electromagnetic. And occasionally Heliotropic.
That is one reason you may see Us taking it easy from time to time. We just have to download; there is only so much Joy anybody can stand without having a Spontaneous Combustion.

Yes! JOY and LOVE, the most ATTRACTIVE things in all the earth, bar none!
