We’ve all experienced it, laughing so hard we’ve cried, like
when looking at eyegotcha’s Facebook page! A good hard laugh, or strong
feelings, cause the muscles around the lachrymal glands to tighten up, forcing
tears to flow. But the tears don’t only go down the face. They also drain
through the tear ducts into the lachrymal sac. From there, they go to the nose,
also making it necessary to also blow our nose. Ha Ha Ha, sniff!
