Medical evidence has now backed up the feeling among office managers that they are smarter than others are.

A research was conducted by the UNSW which states that when a person manages work of other people, there are changes that take place in his brain like protecting its memory and learning centre well into old age.

A link between the size and integrity of a person's hippocampus and managerial experience that a person has in his working life has been established.

When a person turns 80, the hippocampus manages a person's memory and learning.

According to Dr Michael Valenzuela, leader of Regenerative Neuroscience in UNSW's School of Psychiatry, Alzheimer's can be kept away by promoting brain health and being active mentally and this finding gets a better understanding of this.

Brain Sciences UNSW symposium is where this study will be presented and this will mainly focus on `brain plasticity', or the brain's ability to repair, rewire and regenerate itself.

Dr Valenzuela said, "We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus."
