One habit is the secret to Dick Van Dyke's longevity... Find out what it is.

Dick Van Dyke, the legendary American actor and comedian who starred in classic films such as "Mary Poppins" and "Chitty Chitty Bang Bang," celebrated his 100th birthday on December 13, 2025. This beloved actor attributes his remarkable longevity to his positive outlook on life and his avoidance of anger. According to a report published by Science Alert, longevity naturally depends on many factors, including genetics and lifestyle, but there is some truth to what Van Dyke says.

Low stress levels

Numerous studies have shown that maintaining low stress levels and having a positive and optimistic outlook are linked to longevity. One long-term study found that participants who expressed more positive emotions early in life (such as gratitude rather than resentment) lived, on average, 10 years longer than those whose writings were more negative.

A British study also revealed that more optimistic people lived between 11% and 15% longer than their pessimistic counterparts. And in 2022, a study of nearly 160,000 women from diverse ethnic backgrounds showed that women who reported being more optimistic were more likely to live into their nineties than pessimistic women.

The Impact of Anger on the Heart: One possible explanation for these findings relates to the impact of anger on the heart. People who tend to have a more positive or optimistic outlook on life seem to be better able to manage or control their anger. 

This is important because anger can have a number of significant effects on the body. Anger triggers the release of adrenaline and cortisol, the body’s two main stress hormones, particularly in men. Even brief outbursts of anger can negatively impact cardiovascular health.

The added strain that chronic stress and anger place on the cardiovascular system has been linked to an increased risk of conditions such as heart disease, stroke, and type 2 diabetes. These conditions account for approximately 75% of premature deaths. While stress and anger are not the sole causes of these diseases, they are significant contributing factors. So, when Dick Van Dyke says he doesn't get angry, it may be one of the reasons for his longevity.

Negative Effects on Body Cells

There is also a deeper cellular explanation behind stress's impact on longevity, related to telomeres, which are protective caps at the ends of chromosomes (the bundles of genetic information found in human cells). In young, healthy cells, telomeres remain long and strong. But as we age, telomeres gradually shorten and become damaged.

Once they become too worn, cells struggle to divide and repair themselves, which is one reason why aging accelerates over time. Stress is linked to faster telomere shortening, making it harder for cells to communicate and regenerate. In other words, stressful emotions, such as intense anger, can accelerate the aging process.

Important Benefits of Meditation

One study also revealed that meditation, which helps relieve stress, is linked to Positively, it affects telomere length. Therefore, better anger management can contribute to a longer lifespan. Additionally, optimists are more likely to adopt healthier habits, such as regular exercise and a healthy diet, which promotes overall health and longevity by reducing the risk of cardiovascular disease.

Improving Longevity

Contrary to popular belief, trying to "release" anger by punching a bag, yelling into a pillow, or running until the feeling subsides is ineffective. These actions keep the body in a state of heightened alertness, impacting the cardiovascular system and potentially prolonging the body's stress response.

A calmer approach is more effective. Slowing and counting your breaths or using other relaxation techniques (such as yoga) can help calm the cardiovascular system instead of overstimulating it. Over time, this reduces strain on the heart, which can contribute to a longer lifespan without chronic illness.

Positive feelings can also be fostered by cultivating mindfulness in daily life. This allows you to become more aware of what's happening around you. Around him and within him. Positive feelings can also be enhanced by setting aside time to do an enjoyable activity rather than one with a specific goal, which gives a person a boost of positive feelings, which is reflected positively on health.
