Is it possible for someone not to laugh?

I'm not sure! But if people do that, it would be their loss.

Laughing improves the brain"s so called "Reward system" where it release and extend the "Dopamine" hormone levels.

This "Reward hormone" is a neurotransmitter that regulates mood,motivation, attention and learning. It triggers a feeling of pleasure psychologically.

Ray Dart's profile said that he smiled once but didn't like the experience. I'm sure he never laughed. >:-}

U have to laugh its good for u

When my husband who was my boyfriend at the time and I broke up, his family and friends said he didn't laugh for the whole two years we were apart. I guess it's possible.

Personally, I found many times that if I didn't laugh I'd surely cry.

Spok.
