Have you ever wondered if there’s something unique about you that could indicate an unusually long lifespan? It turns out that some signs that you might live to be 100 aren’t what you’d expect. Sure, medical advances and a healthy lifestyle help, but a few unexpected factors could also tip the scales in your favor.

In the 20th century, average life expectancy increased by 30 years – a colossal leap in human history. From 1990 to 2000, the number of centenarians (those who live to 100 years or older) increased by a staggering 51%. The world’s growing community of centenarians is no longer an exclusive club.

But what is actually fueling this phenomenon?

Science suggests that it's not just about eating right or going to the gym. Little things like your daily habits, your mindset, and even your family history play a huge role in determining not only how long you live, but how healthy and happy those years will be.

Here are 9 research-backed signs that you may be destined to live on this Earth for a century.

1. Your mother gave birth to you when you were young.

Did your mother have you before she turned 25? If so, you may have inherited some genes that contribute to longevity. A study conducted at the University of Chicago found that people born to younger mothers are twice as likely to live to 100. This may be due to the higher quality of eggs in younger women, which leads to healthier babies.

2. You feel (and look) younger than your age

Have you ever been told that you look ten years younger than you actually are? If you’re 50 but feel 35, that’s a great sign. Scientists have found that people who feel younger than their chronological age tend to live longer. Why? The energy, optimism, and zest for life you feel can have a positive impact on your overall well-being. Plus, when you’re energized, your body’s systems, like your cardiovascular and immune systems, often function better.

3. You had a child after 40 years old

It turns out that women who become pregnant naturally after age 40 tend to live longer. A study from Boston University suggests that women who have children later in life may have genes that promote longevity, including prolonged fertility. Giving birth after age 44 reduces the risk of early death by about 15%. These genes may keep the body's systems youthful and resilient.

4. You like to drink a cup of tea

If you start your day with a cup of tea, you're already on your way to longevity. Both green and black teas are rich in catechins, which help dilate blood vessels and protect against heart disease. Drinking just one or two cups a day can reduce your risk of heart attack or stroke.

But here’s the trick: skip the milk. Research shows that adding milk to your tea can reduce its cardiovascular benefits. Instead, grab a squeeze of lemon or a spoonful of honey to boost your heart health.

5. You have strong legs.

Your legs are more than just a means of transportation; they are the foundation of a long life. Strong leg muscles improve stability, mobility, and endurance, especially as you age. Research shows that lower body strength is an important factor in longevity, especially because it reduces the risk of falls and hip fractures in older adults.

Harvard researchers have linked strong legs to improved balance, mobility, and overall survival in old age. So every step you take today is a step toward a longer, healthier future.

6. You don't snore.

Snoring may not just be an annoyance to your partner—it may be a warning sign of sleep apnea, a condition in which your breathing is briefly interrupted while you sleep. People with severe sleep apnea are at higher risk for high blood pressure, heart problems, obesity, and depression. Research shows that those who avoid sleep apnea attacks are much more likely to reach a score of 100.

Studies have shown that sleep apnea significantly increases the risk of early death. So if you're a sound sleeper, that's a great sign of your future longevity.

7. You are the life of the party

If you're the type of person who always makes sure you're surrounded by attention, you may have the secret to a long life. Outgoing, optimistic people who are surrounded by friends tend to have lower levels of the "stress hormone" cortisol. Chronic stress not only weakens the immune system, it also accelerates aging and impairs brain function.

Optimism and strong social connections are important factors in longevity. A 2019 study by Boston University found that optimists live an average of 11-15% longer than pessimists.

As the Dalai Lama wisely said, “ The purpose of life is to be happy ,” and that happiness may just help you live a little longer.

8. You are a woman

Good news, ladies: Women consistently outlive men around the world. On average, women tend to live longer in almost every society and culture. Although scientists aren’t entirely sure why, leading theories point to sex hormones and the protective effects of two X chromosomes. Some studies also suggest that women have stronger immune systems, making them more resistant to infectious diseases.

In fact, research shows that women's innate and adaptive immunity is superior to men's, which may contribute to their longevity.

9. You go through menopause after age 52.

If you have menopause later than usual, it may be a promising sign of longevity. Research has shown that women who enter menopause after age 52 have a lower risk of heart disease. This protective effect may provide you with additional years of health and vitality.

So, what’s the secret to living to 100? It’s not just luck or genetics – it’s how you live, how you feel, and even how you interact with other people. Every little piece plays a role in the puzzle of living a long and happy life. And who knows? With these signs, you might just make it to 100!
