Did you ever see a tigre brushing his teeth with a paste? Why you do ?????

Humans seem to be the onliest dysfunctional species on Earth, don`t? Animals, as far as they got not "civilized" they do not see any doctor. Please folks, God gave you a brain to use it, s-he did not design you as a copy machine, just repeating and repeating any kind of shit somebody tells you to do.
