A new study involving reports from more than 700,000 U.S. veterans theorised that people who adopt the undermentioned healthy lifestyle habits by middle age can expect to live substantially longer than those with few or none of these habits. These habits include: being physically active, avoiding smoking, properly managing stress, being free from opioid addiction, having a good diet, not regularly binge drinking, having good sleep hygiene, and having positive social relationships. According to the results, men who have all eight habits at age 40 would be predicted to live an average of 24 years longer than men with none of these habits. For women, having all these healthy lifestyle factors in middle age was associated with a predicted 21 additional years of life compared to women with none of these habits.
