HAHAHA *tear*?

Question

Why do you start crying when you laugh too hard? That happened to me three times today :)

Answer 1

Good question! I will go have a search and see if I can come up with an answer.

I found this quote..."Laughing to the point of tears involves emotions, and
although scientists are discovering a lot of interesting things about
emotions, they're hard to study scientifically"

Not a lot of help!! The site below was interesting but it does not give an answer...:D

Answer 2

Increased pressure in the head, actually forces tears from the ducts.
