How to Live to 100

We’re living longer than ever before, thanks to healthier lifestyles and medical advancements such as vaccines and antibiotics. The average life expectancy in Canada, currently 82 and rising, has increased by 11 years since 1960. Of course, reaching a ripe old age is significantly more rewarding if you feel fit and healthy, and your life is full.

Researchers who study longevity and health have concluded that people who live the longest share some common characteristics in where and how they live, and how proactively they take care of themselves. “Longevity is useless if it means more years incapacitated in a home,” says Benjamin Zendel, a professor at Memorial University of Newfoundland and Canada Research Chair in Aging and Auditory Neuroscience.

Follow these 45 proven—and often surprising—tips on how to live to 100, happily.

Watch your weight

An analysis in the Annals of Internal Medicine of three long-term studies found that being overweight at any time in adulthood can shorten your life significantly. If you’re heavy, losing just five to 10 per cent of your body weight will help prevent life-threatening chronic diseases such as diabetes.

Brush your teeth

“There’s a correlation between poor oral health and the risk of other conditions, such as cardiovascular disease and diabetes,” says Dr. Howard Tenenbaum, the dentist-in-chief at Toronto’s Sinai Health System. Bacteria from the mouth can enter the bloodstream and spread. Even the molecules involved in fighting oral infection appear to exacerbate inflammation elsewhere in the body.

Find out exactly how long you should be brushing your teeth.

Get your eyes checked

According to a 2014 study in the Journal of the American Medical Association, the reduction in independence from vision loss has an impact on life­span. In the study, seniors who were gradually losing their vision—that is, by one eye-chart line per year—were 16 per cent more likely to have died eight years later. The researchers believe that correcting vision or learning strategies for adapting to vision loss, like how to read a grocery list with a magnifying tool, can reduce this risk.

Breathe deeply

Lung capacity begins to decline around age 35 as your airways lose elasticity, your posture changes and your diaphragm loses strength, making it more difficult to take in the oxygen your body needs to stay active and healthy. Slow these changes by exercising your lungs for five or 10 minutes a day: breathe deeply, concentrating on lowering your diaphragm—the muscle under your lungs that allows these organs to expand. Gradually extend the time it takes you to inhale and exhale.

Here’s what might happen when you start meditating every day.

Don’t overmedicate

A 2015 study of over 5,000 Spanish seniors revealed that patients on the most pills died the earliest. Although it doesn’t prove that multiple prescriptions (known as “polypharmacy”) are the cause of an earlier death, what’s known is that we’re more vulnerable to drug interactions and side effects as we age. Even common medications like ibuprofen can lead to ulcers, kidney disease or cardiovascular events if taken long term. Bring a list of all your prescriptions to your next GP appointment and find out if you can reduce or eliminate anything.

These everyday medication mistakes could be making you sick.

Tend to your tootsies

A potential complication of diabetes, a disease shared by 2.3 million Canadians, is open sores on the feet. A 2019 Australian study linked diabetic foot ulcers to a death up to 15 years earlier than the average. Check your feet regularly for redness or breaks in the skin, and see a health-care professional if you have concerns.

Here are the subtle signs of disease your feet can reveal.

Replace worn hips

If you’ve been advised to have hip surgery but put it off because you don’t relish the long recovery, you might reconsider. In Sweden, almost 132,000 patients who had a total hip replacement had a higher chance of being alive 10 years later. The researchers couldn’t pinpoint the reasons but believe many factors are at play, noting that a hip replacement typically improves mobility and lessens pain.

Cut back on booze

Alcohol consumption was blamed for an estimated 14,800 deaths and 88,000 hospital visits in 2014. If you’re female, limit yourself to 10 drinks per week, and no more than two a day. If you’re male, don’t exceed 15 per week, or three a day.

Here’s what happens when you drink a glass of wine every night.

Go ahead, drink more coffee

This beverage is linked to longer life, possibly because the caffeine content helps our bodies fight chronic inflammation. Count your cups and stop at five per day; otherwise you increase your risk of cardiovascular disease. If you prefer decaf, you won’t get the caffeine benefits, but you’ll still be taking in antioxidants.

Here’s how to make your coffee habit even healthier.

Embrace housework (you’ll thank yourself!)

Even light-intensity physical activity, like sweeping the floor or washing dishes, appears to lengthen your life—with every minute you do, your chances of dying go down, according to a 2019 report in The BMJ. “This suggests that older people and those who are not able to be physically active at higher intensities will still benefit from just moving around,” wrote one of the report’s authors, who was from the Norwegian School of Sport Sciences.

You’ll gain more health benefits when physical activity is combined with mental stimulation and social interactions. “In my lab, we use the tag line ‘lifestyle cross-training,’” explains psychologist Stuart MacDonald at the University of Victoria, where he investigates the neuroscience of aging. “There’s some basic science suggesting that your memory functions better if you’re also physical. And if you choose an activity where you get to see your friends, you’re more likely to keep doing it.”

Here are the telltale signs you need to move more.

Find excuses to walk

Many municipalities offer themed walking tours. Since participants can learn history or view gardens while being physically and socially active, it also counts as a “lifestyle cross-training” strategy. According to research on men and women over 40, published in the British Journal of Sports Medicine, just one hour of leisure walking per week appears to reduce the death rate by 18 per cent compared to totally inactive individuals.

Here’s what happens to your body when you start walking 10,000 steps a day.

Make friends

“If you’re socially isolated, you tend to have a heightened inflammatory response. Left unchecked, inflammation gets manifested as disease,” says MacDonald. Research at the University of Helsinki in 2018 showed that lonely people tracked over seven years were much more likely to have a heart attack (43 per cent) or stroke (39 per cent).

Turn up the heat

The more often middle-aged men in Finland visited saunas—from once a week to daily—the lower their death rates over a 20-year period. Sauna use appears to lower blood pressure and protect blood vessels. (It may not be recommended if you’re recovering from a heart attack or have angina.)

Try these natural remedies for high blood pressure.

Manage stress

“If you have protracted stress for a long time, you tend to have elevated levels of cortisol,” says MacDonald. “It’s been shown that your hippocampus atrophies when you bathe it in cortisol over a long time.” Prolonged exposure to emotional stress can reduce survival rates for people with health conditions, raising their death rate over a four-year period by 39 to 43 per cent. Try seeing a problem as a challenge you can tackle and learn from.

Make sure you’re not ignoring these silent signs of stress.
