You are only as old as you feel, as the saying goes, and new research suggests that feeling younger than you are could have health benefits. A study has found that people who felt younger than their actual age had a lower death rate than people who felt their age or older. 
 
 
 
 How old we feel often reflects our physical and mental well-being. Many people have a self-perceived age that is different to their actual chronological age. How old we feel often reflects our physical and mental well-being. Many people have a self-perceived age that is different to their actual chronological age. 
 
 The research letter, published in JAMA Internal Medicine, observed a lower death rate in older people who felt 3 or more years younger than their actual age, compared with participants who felt their actual age or more than 1 year older. 
 
 "Self-perceived age reflects appraisals of health, physical limitations, and well-being in later life," write the authors of the study, from University College London in the UK. "Older people typically feel younger than their chronological age, and it is thought that those who feel younger than their actual age have reduced mortality." 
 
 A number of social experiences have been identified that affect self-perceived age over time. Role transitions and off-time events such as becoming a parent at an early age, experiencing stress, the development of serious health problems such as heart problems or cancer - all have been found to speed up self-perceived aging. 
 
 Authors Isla Rippon and Dr. Andrew Steptoe analyzed data from the English Longitudinal Study of Ageing in 2004-2005 for 6,489 participants. They measured the self-perceived age of the participants by asking the question, "How old do you feel you are?" 
 
 The average chronological age for the participants was 65.8 years, and the average self-perceived age was 56.8 years. 
 
 Participants were divided into three groups: those whose self-perceived age was close to their actual age (25.6% of participants), those who felt more than 1 year older than their actual age (4.8% of participants), and those who felt 3 or more years younger (69.6% of participants). 
 
 The researchers then recorded all mortality including deaths from cancer and cardiovascular disease up until March 2013. The average follow-up period for the participants was 8.25 years. 
 
 They found that the mortality rate was 14.3% among adults who felt younger than their actual age. In comparison, participants with a self-perceived age close to their actual age had a mortality rate of 18.%, and participants who felt older than their actual age had a mortality rate of 24.6%. 
 
 'Self-perceived age has the potential to change' 
 
 There was a strong association between self-perceived age and death caused by cardiovascular disease, although not between self-perceived age and cancer death. 
 
 "Although baseline health, physical disability, and health behavior accounted for some of the association, after adjusting for all covariates, there remained a 41% greater mortality hazard in people who felt older than their actual age compared with those who felt younger than their actual age," write the authors. 
 
 The authors also tested for reverse causality by excluding participant deaths within 12 months of the study's commencement. They state that this suggested the association was not a result of participants perceiving their age as older than their actual age due to being in the terminal phases of their lives. 
 
 The proportion of study participants who felt older than their actual age was relatively small in comparison with the other self-perceived age groups, and so further research may be needed to validate these findings. 
 
 The authors state that the mechanisms underlying these associations merit further investigation as well. They suggest that greater resilience, sense of empowerment and will to live, as well as specific health behaviors such as adhering to medical advice, could explain the lower mortality rates in people feeling younger than their actual age. 
 
 "Self-perceived age has the potential to change, so interventions may be possible," conclude the authors. "Individuals who feel older than their actual age could be targeted with health messages promoting positive health behaviors and attitudes toward aging." 
 
 Recently, Medical News Today reported on a study suggesting that running for exercise could slow the aging process. Senior citizens who run several times a week expend the same amount of energy as a typical 20-year-old when walking. ||||| Also Meets CME requirements for:

– If you eat well and exercise, you'll probably feel younger than your chronological age. But new research suggests that simply feeling younger than your age—even when accounting for other longevity factors, such as alcohol intake, wealth, illness, education, and smoking—improves longevity, reports Medical News Today. Studying 6,489 participants in the English Longitudinal Study of Aging, researchers report in the journal JAMA Internal Medicine that mortality was only 14.3% among those who felt younger than their age, but was 18% for those who felt their age, and 24.6% for those who felt older. "Someone who feels younger is possibly healthier than someone who feels older—they have fewer diseases, they may be more mobile," a researcher tells CBS Philadelphia. The study couldn't connect self-perceived age with death by cancer, but did establish a strong link between self-perceived age and fatal cardiovascular disease. Factors that speed up self-perceived aging include becoming a parent at an early age, experiencing stress, and developing serious health problems such as cancer. Still, more than 66% of participants say they felt at least three years younger than their chronological age. According to the study, older people who feel old may well slow the aging process by adopting a fresh outlook: "Interventions may be possible," the authors say. "Individuals who feel older than their actual age could be targeted with health messages promoting positive health behaviors and attitudes toward aging."
