A study from the UK and published in JAMA on 6500 people aged 52 and above documented that if you felt older than your actually age that your mortality over the 8 year study period was higher. Seventy percent of this group felt at least 3 years younger, 25% felt the same age, and 5% felt older. The mortality rate for those people feeling younger than their actual age had a 14% mortality, those feeling the same age had a 19% mortality, and those feeling older had a 25% mortality!
