Aging is inevitable, but how we age is something we have more control over than many people realize. Research in gerontology and positive psychology consistently shows that certain habits can accelerate aging, while letting go of them can help people stay energetic, engaged, and vibrant well into their later decades.
For those in their 70s — or approaching that milestone — here are 10 habits that experts say are worth leaving behind.
1. Living a sedentary lifestyle
One of the most well-documented findings in aging research is that physical inactivity accelerates decline. According to the World Health Organization, older adults who maintain regular physical activity have better cardiovascular health, stronger bones, and improved mental well-being.
That doesn’t mean you need to run marathons. Even daily walks, gentle yoga, or swimming can make a significant difference. The key is consistent movement — staying active is one of the strongest predictors of healthy aging.
2. Isolating yourself socially
Social isolation is a serious health risk for older adults. Studies published in journals like The Lancet have found that loneliness in later life is associated with increased risks of dementia, heart disease, and depression.
Maintaining social connections — whether through community groups, family relationships, or friendships — is essential. Psychology research suggests that people who stay socially engaged tend to feel younger and more purposeful regardless of their actual age.
3. Holding onto grudges
Carrying resentment takes a measurable toll on both mental and physical health. Research from the Journal of Behavioral Medicine has linked chronic unforgiveness to higher blood pressure, increased stress hormones, and weakened immune function.
Letting go of old grudges isn’t about excusing bad behavior — it’s about freeing yourself from the burden. Many psychologists recommend forgiveness practices not for the other person’s sake, but for your own health and peace of mind.
4. Neglecting your diet
Nutrition becomes even more important as we age. The body’s ability to absorb nutrients changes over time, and poor dietary habits can accelerate everything from cognitive decline to bone loss.
Research supports diets rich in fruits, vegetables, lean proteins, and healthy fats — patterns like the Mediterranean diet have been consistently linked to better outcomes in older adults. Staying hydrated is equally important, as the sensation of thirst tends to diminish with age.
5. Refusing to adapt to change
Psychological rigidity — the unwillingness to adapt to new circumstances — is associated with poorer mental health outcomes in later life. Studies in developmental psychology show that cognitive flexibility is a key factor in resilience and well-being at every age.
Whether it’s learning new technology, adjusting to retirement, or embracing a different living situation, staying open to change helps keep the mind sharp and the spirit engaged.
6. Skipping regular health checkups
Preventive healthcare becomes increasingly vital in your 70s. Many serious conditions — including certain cancers, heart disease, and diabetes complications — are far more manageable when caught early.
Experts recommend staying on top of regular screenings, dental visits, eye exams, and medication reviews. It’s not about being anxious about health — it’s about being proactive.
7. Overcommitting out of guilt
Many people in their 70s have spent decades putting others first. While generosity is admirable, research on caregiver burnout shows that chronic overcommitment leads to exhaustion, resentment, and declining health.
Learning to set boundaries and say no is a skill that serves people well at any age, but it becomes especially important when energy and stamina are more limited. Protecting your time and energy isn’t selfish — it’s necessary.
8. Dwelling on the past
Nostalgia can be comforting in small doses, but excessive rumination about the past is linked to depression and anxiety. Psychological research suggests that people who focus primarily on past regrets or lost opportunities tend to experience lower life satisfaction.
A healthier approach, according to positive psychology, is to practice gratitude for past experiences while staying focused on the present. Mindfulness techniques have been shown to be particularly effective for older adults in maintaining a positive outlook.
9. Ignoring mental health
There’s a generational tendency among older adults to dismiss mental health concerns or view seeking help as a sign of weakness. But depression and anxiety are not normal parts of aging — they’re treatable conditions.
Research shows that therapy, including cognitive behavioral therapy, is effective for older adults. Mental health is just as important as physical health, and addressing it can dramatically improve quality of life in your 70s and beyond.
10. Believing it’s too late to try something new
Perhaps the most limiting habit of all is the belief that your best days are behind you. Research on neuroplasticity — the brain’s ability to form new connections — shows that the brain remains capable of learning and growing throughout life.
Whether it’s picking up a musical instrument, learning a new language, starting a creative hobby, or even going back to school, there’s strong evidence that novel experiences keep the brain healthy and contribute to a sense of vitality.
The 70s can be one of the most fulfilling decades of life — but only if we’re willing to let go of the habits that hold us back. The science is clear: it’s never too late to make changes that support a vibrant, engaged, and healthy life.
