The quest to prolong life has always intrigued humanity. Over time, scientists have made significant strides in understanding the factors that contribute to longevity. Although genetics accounts for about 25% of our lifespan, lifestyle choices and mental attitudes play a much more important role.

Here are 10 signs that may indicate that a person is on the path to a long and healthy life.

1. Belonging to the female gender

Around the world, women tend to live longer than men. This pattern even extends to many animal species. Research in the United States suggests that estrogen, a hormone predominant in women, has anti-inflammatory properties and strengthens the immune system. Conversely, testosterone in men can weaken immune responses.

Dr Stephen Austad, an aging researcher, notes: "Women's immune systems age more slowly than men's, which helps them live longer."

2. Youthful appearance

Looking younger than your chronological age is often a sign of longevity. This phenomenon is related to the length of telomeres - protective shells on chromosomes that shorten with age.

"Telomere length is a biomarker of aging," says Nobel Prize-winning scientist Dr. Elizabeth Blackburn.

3. Vegetarian diet

Research from Harvard shows that vegetarians often live longer. Cutting out meat and dairy can slow down cellular aging, allowing the body to focus on repair and protection.

A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can add years to your life. Diets like the Mediterranean diet, which emphasizes fresh, unprocessed foods, have been shown to reduce the incidence of chronic diseases and increase life expectancy.

Nutrition expert Dr. T. Colin Campbell says, "A plant-based diet protects against many chronic diseases and may prolong life."

As Hippocrates said: “Let food be thy medicine, and medicine be thy food.”

4. Normal hemoglobin level

Maintaining normal hemoglobin levels is critical to living a long life. Both high and low levels can accelerate aging and shorten lifespan.

Dr. Bruce Ames, a biochemist, emphasizes: “Balanced hemoglobin levels ensure efficient oxygen transport and reduce oxidative stress, which is vital for longevity.”

5. Healthy Gut

Centenarians often have strong gut health, which helps with digestion, vitamin production, and immune health. The Mediterranean diet, rich in vegetables, seafood, fruits, and greens, supports gut health.

6. Slenderness

Being overweight increases your risk of dying. Being thin is associated with longer life because being overweight increases your risk of chronic diseases like diabetes and heart disease, which accelerate aging.

7. An optimistic outlook on life

Optimists live 10-15 years longer than pessimists because positive thinking reduces stress and promotes a healthy lifestyle.

Having a cheerful personality can do wonders for your life expectancy. Research has shown that optimistic people tend to live longer. A positive attitude reduces stress, strengthens your immune system, and promotes overall well-being.

As Norman Vincent Peale said, "Change your thoughts and you change your world."

8. Regular physical activity

Exercise is a key factor in longevity. Regular physical activity strengthens the heart, improves lung function and maintains muscle mass.

Being active is the best thing you can do for your health and longevity.

9. Intellectual activity

People who do intellectual work tend to live longer. Constant brain activity slows down the decline of cognitive abilities and reduces the risk of developing dementia.

Lifelong learning and mental health challenges support brain health and prolong life.

10. Family and communication with others

Loneliness can shorten life expectancy, while strong social connections can increase it. Research in the UK shows that people with strong social networks are healthier and live longer.

Socializing and relationships are as important to survival as factors like not smoking and being physically active.

Life expectancy is influenced by a combination of genetic, lifestyle and social factors.
