On December 13, legendary American actor and comedian Dick Van Dyke turned 100. The star of the cult films Mary Poppins and Chitty Chitty Bang Bang has repeatedly said that he explains his remarkable age with a simple rule: positive thinking and the absence of anger, according to ScienceAlert.
Why life without anger promotes longevity
Although longevity depends on many factors, including genetics, lifestyle, and medicine, science partially supports the actor’s words. Studies show that low stress levels and an optimistic outlook on life are closely linked to longer life expectancy.
One of the most well-known examples is the so-called Nun Study. Back in the 1930s, 678 young women wrote autobiographies when entering a convent. More than 60 years later, scientists compared these texts with the women’s health outcomes. Those who expressed gratitude and positive emotions more often in their youth lived an average of 10 years longer than pessimists.
British scientists have also found that optimists live 11–15% longer. A large-scale 2022 study involving 160,000 women showed that people with positive thinking are more likely to live to 90 and beyond.
One explanation lies in the effect of anger on the heart. Anger triggers the release of adrenaline and cortisol, stress hormones that impair cardiovascular function even during short emotional outbursts. Chronic stress is associated with a higher risk of heart attack, stroke, and type 2 diabetes, conditions responsible for up to 75% of premature deaths.
There is also a deeper, cellular mechanism. Stress accelerates the shortening of telomeres, the protective caps at the ends of chromosomes. When they wear down, cells regenerate less effectively and aging speeds up. At the same time, meditation and emotional regulation are associated with longer telomeres.
An additional benefit of optimism is healthier habits. Positive people are more likely to exercise regularly and eat better. Dick Van Dyke himself, even at 100, tries to work out at least three times a week.
Scientists advise against releasing anger aggressively. Instead, they recommend calming breathing techniques, relaxation practices, or yoga. This approach reduces strain on the heart and may help extend life.
