Picture the life I want at 80, then plan backward from it.
Who
Peter Attia is a physician who trained in surgery at Johns Hopkins and spent time at the National Cancer Institute before working as a consultant at McKinsey. He later started a medical practice focused on longevity and hosts the podcast The Drive. In 2023 he published Outlive: The Science and Art of Longevity. His work is about healthspan, the years in which you stay physically and mentally capable, rather than lifespan alone.
Operating rules
Plan backward from the end. His “Centenarian Decathlon” asks people to list the everyday things they want to still do late in life, such as carrying groceries, climbing stairs or getting up off the floor. Then you work out what you need to build now to still have that ability decades later.
Act early, not late. He calls his approach Medicine 3.0. Instead of waiting for problems to appear, it treats long-term risk as something to work on years in advance.
Treat health as a portfolio. Exercise, nutrition, sleep and emotional health each matter. Over-investing in one while ignoring another is a common mistake.
Count emotional health. In Outlive he writes candidly about his own struggles and argues that a long life is not worth much without the emotional health to enjoy it.
What I borrowed
Backcasting. It is the same logic I use for work: describe the end state, then work back to this quarter. It is also why my early morning runs stay at an easy pace. I am not training for a race. I am training for a much later decade.
What I won’t copy
The level of measurement. I find his way of thinking more useful than any dashboard. This note is about how he thinks, not medical advice, and anything specific to a body belongs in a conversation with one’s own doctor.
