Episode Summary: In this episode, I explore whether it’s ever “too late” to change your health future—and why the science suggests that earlier is better, but later still matters. 

Can you still change your future? The answer is hopeful, but nuanced. Younger listeners may assume they have plenty of time, while older listeners may wonder whether the damage has already been done. In both cases, the evidence points to a more useful truth: some risks accumulate over time, some damage may be partly repaired, and many future outcomes can still be changed.

I begin with a personal update about using EMDR to address exercise-related fear. At 69, I’ve found that it has helped me feel more confident and enjoy intense exercise more. Would it have been better to try it decades ago? Probably. But that does not mean it was too late to benefit now.

The episode then walks through a five-part framework for thinking about health changes. First, some changes are best made early because damage accumulates. Blood pressure is a clear example: long-term cumulative blood pressure exposure in young adulthood has been linked with later cardiovascular disease risk, which is why “my arteries are keeping score now” is such an important message.  Glaucoma follows a similar logic: elevated eye pressure can silently damage the optic nerve, so early detection and treatment matter.

Second, some damage may be partly repaired. Smoking cessation is the clearest example. Lung cancer risk declines the longer someone has stopped smoking, although prior smoking risk does not disappear completely.  I also discuss the Lifestyle Heart Trial, where intensive lifestyle changes were associated with regression of coronary atherosclerosis and fewer cardiac events over time, while also noting that the study was small and required major changes that may not be realistic for everyone. 

Third, even when we cannot erase the past, we can still protect the future. The Diabetes Prevention Program showed that lifestyle changes reduced the risk of developing type 2 diabetes by 58% overall and 71% among adults over age 60.  The UKPDS also reminds us that early glucose control after diabetes diagnosis can have lasting benefits, especially for complications involving the eyes, nerves, and kidneys. 

Fourth, it is never too late to build certain capacities. Strength training is a powerful example. In one study of frail adults up to age 96, high-resistance training led to major strength gains and improved walking speed.  That does not mean we are trying to become bodybuilders at 90. It means we are training for independence, balance, confidence, and the ability to keep doing the things that make life meaningful.

Finally, timing may matter, but sometimes we do not yet know how much. Social connection is strongly tied to health and happiness, as shown in the Harvard Study of Adult Development, but we do not know exactly how much risk can be reversed by building new relationships later in life.  Sauna use has also been associated with lower cardiovascular and cognitive risk, but it is less clear whether benefits require lifelong use or can still meaningfully begin later. The practical question becomes: does this activity also bring you joy now?

Takeaways: Earlier is better, but later is not too late. Start by asking what part of your future you can still influence from here. Check your blood pressure, see your eye doctor, consider strength training, reconnect with a friend, or address a fear that has been holding you back. The goal is not perfection—it is progress, and there is still time for that.
