Early retirement, before the age of 62, has been associated with higher mortality risk in some instances. A study of Shell Oil employees found that those who retired at 55 and lived to be 65 died 37 percent sooner than those that retire at 65. And in general, people who retire at 55 are 89 percent more likely to die within ten years than those that retire at 65.
Social Security has noticed this trend, as well. Men that retire at 62 have a 20 percent higher likelihood of death than the general population. However, retiring early for women causes no increase in mortality rates.
