Presidents Stress Aging

Former President Bill Clinton before and after his term in office. 

I've always heard that presidents dramatically age during their term in office but why? Dr. Jay Olshansky, a sociologist at University of Illinois-Chicago studied as why presidents rapidly age during their term.
Dr. Olshansky research found that it is normal to age it's apart of life. The thing is that most presidents are in their 50's when entering their presidency. So, during this stage of life it is more prominent for physical to drastically change to show age. It is shown through numerous presidents that it is a significant change. Recently reelected president, President Barack Obama has shown an increase of gray hair and sunken eyes. Also, former President Jimmy Carter had baggier eyes by the end of his term. A huge factor as to why its a more significant physical change is that being president is a highly stressful job. Especially now, with gas prices on the rise, the economy on a serious reconstruction and dealing with getting our troops back. It is plenty of stress that one person has to handle.
