Staying healthy as you age comes down to five habits: not smoking, staying active, keeping a healthy weight, eating well, and limiting alcohol. A Harvard study published in Circulation in 2018 followed more than 120,000 adults and found that people who kept all five habits gained about 14 extra years of life if they were women and 12 years if they were men, measured from age 50. They were also 74 percent less likely to die during the study. After 65, add two more: strength and balance work to prevent falls, and staying socially connected. Below is what each habit means in practice and how much of it you actually need.
What Each Habit Looks Like in Practice
| Habit | What It Takes |
| Physical activity | 150 minutes a week of brisk walking |
| Strength training | 2 days a week, all major muscle groups |
| Balance work | Standing on one foot, heel-to-toe walking |
| Healthy weight | BMI between 18.5 and 24.9 |
| Diet quality | Mostly whole foods, vegetables, and fish |
| Alcohol | Moderate at most, less is better |
| Smoking | None, and quitting helps at any age |
Why Strength and Balance Matter After 65
The CDC recommends that adults 65 and older get 150 minutes of moderate activity each week, plus two days of muscle strengthening and regular balance work. Balance is the part most people skip. More than 14 million adults 65 and older, roughly 1 in 4, fall each year according to the CDC, and fewer than half tell their doctor. Strong legs and steady balance prevent the fall that changes everything.
Catch Problems Before They Grow
Habits do most of the work, but not all of it. CDC data from 2023 shows 93 percent of adults 65 and older have at least one chronic condition. Most start quietly. High blood pressure, high cholesterol, and rising blood sugar produce no symptoms for years. A yearly annual physical catches them early, when habits still work and medication may not be needed yet. If you already manage a condition, chronic disease management keeps it stable.
Final Thoughts
This does not require a dramatic overhaul. Walk most days, lift something twice a week, eat mostly real food, and keep your yearly checkup. The Circulation study found the benefit grows with each habit you add, so starting with one still counts. Call Yorktown Health Lisle to book a physical and pick one change to start with.
