Why we laugh, according to science
A woman is having a terrible time in labor and suddenly yells, “I shouldn't! I could not! Nope! I can't !"
Don't worry," says the doctor. "Those are just contractions"
Until now, various theories have tried to explain what makes something funny enough to make us laugh.

After reviewing more than a hundred articles, my study produced a new possible explanation: laughter is a tool that nature may have provided us to help us survive.
I looked at research papers on theories of humor that provided significant insights into three areas: the physical characteristics of laughter, the brain centers involved in laughter production, and the health benefits of laughter.
More than 150 articles provided evidence of important characteristics of the conditions that make humans laugh.

By organizing all the theories into specific areas, I was able to condense the process of laughter into three main steps: bewilderment, resolution, and a possible signal that there is no longer any danger , as I will explain later.
This raises the possibility that natural selection may have preserved laughter for the past millennia to help humans survive. It could also explain why we are attracted to people who make us laugh.

It is about finding ourselves in a specific situation that subverts our expectations of normality. Read More…
