So chemical analysis means one has to test to find out the characteristic. So this I have seen, one doctor friend, he was keeping one dysentery stool in a plate, on his table, I saw. "What is this doctor?" He said, "Oh, it is to be tasted... It is dysentery stool". So they taste it. They have to. They take fish... Everyone, medical men know. So this hog's business is to eat stool, and as soon as he gets fatty, then sex. And that sex has no discrimination. You will see, a hogs, he does not care whether mother, sister or anyone, daughter. It doesn't matter. So this is hog civilization. Simply eating and getting strength of the senses and enjoy it.
