A team of Japanese scientists have found scientific proof that people doing exercises appear to perform better when another person compliments them.
The team had previously discovered that the same area of the brain, the striatum, is activated when a person is rewarded a compliment or cash.
Their latest research suggests that when the striatum is activated, it seems to encourage the person to perform better during exercises.

In everyday life people need to get consensus and reward to those around them. I am convinced that this is due to the fact that the individual cannot be detached from the social group to which he belongs. People need to feel part of the social group and have to do whatever it takes to stay inside.
