Some years back, Antonio Damasio, a famous neuroscientist studied people with the injury in the part of the brain where emotions are generated. He found out all people had one thing in common i.e. they could not make decisions. They were able to describe what they should be doing logically. However, they found it very difficult to make even simple decisions, such as what to eat.
Research reveals that the decisions that we think are logical are greatly influenced by our emotions.
