For a while now, I’ve been working on an ebook about making digital health more useful and usable for older adults.
(Don’t hold your breath, I really have no idea when it will be done. I can only work on it for about an hour every weekday.)
In reflecting on the health innovation conferences and conversations in which I’ve participated these past few years, I found myself musing over the following two questions:
1. What is health?
2. What does it mean to help someone with their health?

After all, whether you are a clinician, a health care expert, or a digital health entrepreneur, helping people with their health is the core mission. So one would think we’d be clear on what we’re talking about, when we use terms like health and health care.
But in fact, it’s not at all obvious. In practical parlance, we bandy around the terms health and health care as we refer to a wide array of things.
Actually defining health has, of course, been addressed by experts and committees. The World Health Organization’s definition is succinct, but hasn’t been updated since 1948:
“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.”
A more recent attempt to define health, described in this 2011 BMJ editorial, proposed health as “’the ability to adapt and self manage’ in the face of social, physical, and emotional challenges.”
This left me scratching my head a bit, since it sounded more like a definition of one’s resilience, or self-efficacy. Which intuitively seem much related to health (however we define it), but not quite the same thing.
I found myself itching for a definition of health that would help me frame what I perceive as the health – and life – challenges of my older patients.
