think of it this way. we have i think everything 2 in our human body. 2 eyes, 2 ears, 2 brains, 2 hands, 2 feet, two ribs? i don\'t know. how come we only have like 1 heart and 1 mouth, 1 tongue? 1 butthole, 1 penis, or if a woman 1 vagina? oh yeah, 1 stomache, 1 belly button, 1 intestine? shrugs...i am no doctor so don\'t know.
so the 1 mouth, and the 1 tongue in there taste food and drink which goes to the 1 stomache to digest the food. and the waste say like poop went out the butthole. gas also went out the butthole. multi-function of the butt. and waste like pee went out the penis if you are a man and vagina if you are a woman. multi function of the penis and vagina beside peeing is masturbation too. if penis, you can ejaculate cum and feel good. woman can also finger their vagina like rubbing the clitoris to feel good too.
anyway, once the tongue slide back into the throat and return back to the right side of the chest and become a right heart. i think everything in our body should be 2. gone are the butthole, penis, if woman vagina, stomache, maybe intestine...gone are the mouth, teeth, gum too...oh yeah, gone are also the testicles too...sure two balls but i think it was created for masturbation and ejaculation. maybe left heart help created extra ball beside the tongue which created the right ball...
oh yeah, i think gone are also the throat, and maybe the neck?
add: one more thing, how about the nose? only one nose, sure there are 2 nostrils...hmmm...2 lungs to help it breathe? maybe left heart helps created the left lung while the tongue created the right lung to help it breathe...maybe gone is also the nose? shrugs...i dunno.
