Why laughing is contagious?

[Anonymous]

Why do we laugh when we see others laughing?

Yawning is contagious & when it comes to laughing what might be funny to someone might not be funny to someone else. On the other hand if you are in a group & someone cracks a joke most of the time someone is going to laugh but remember this he who laughs last thinks the slowest.

It sort of is how our brains are wired. When we see other people laughing we want to join in. In other words we also don’t want to be left out. And when we see others laughing joining in can help you feel included. It is something that has been wired through our brains for centuries.

I think we have a natural thing to be part of a group and emotions are a thing that we feel and can share.

therefore laughter will often make us laugh without even knowing the reason for it.

I do not know the Science behind it, however, I know the outcome from a woman who sighs from laughing at another’s corny jokes…
