Healthspan over lifespan: why experts care about your last decade
Attia, Sinclair and Vonda Wright all argue that the goal is more years of vigorous, independent life rather than simply more birthdays. This shifts which interventions matter, favoring mobility, strength and cognition over simply avoiding death.
What is the difference between lifespan and healthspan, as Vonda Wright describes it? Show answer
Lifespan is how long you live. Healthspan is how long you feel strong, active, mobile and joyful.
Why does Peter Attia find the standard medical definition of healthspan unhelpful? Show answer
It defines healthspan as time free of disability and disease, so by that measure he has the same healthspan as 30 years ago, when he was far more capable physically and mentally.
What are the three dimensions of healthspan in Attia's definition? Show answer
Physical, cognitive and emotional: maintaining muscle, mobility and freedom from pain, preserving mental sharpness, and coping well with distress.
Why does Attia rank emotional health so highly? Show answer
He argues that without it none of the other work matters, and that even the fittest person can be in total despair.
What is the centenarian Olympics? Show answer
Attia's tool of defining the physical tasks you want to do at 80, 90 or 100, then reverse-engineering your training in your 40s, 50s and 60s to keep them.
What does Attia call the root of the other major killers? Show answer
Metabolic dysfunction. He says more than 50% of Americans are on its spectrum without knowing it.
What four modifiable causes of metabolic dysfunction does Attia name? Show answer
Excess carbohydrate intake, too little muscle to store and burn glucose, sleep deprivation and chronic stress.
What ending does David Sinclair want in place of a slow decline? Show answer
He wants people to stay young longer and have a life of vitality that ends quickly and peacefully, rather than a slow, disease-ridden death.
What does Wright say causes frailty? Show answer
Not moving. In her view people don't get frail because they age; they age because they get frail.
What does Wright's FACE protocol stand for? Show answer
Flexibility and mobility, Aerobics, Carry a load, and Equilibrium and foot speed.
Why does Wright call muscle important for longevity? Show answer
Contracting muscle makes the body produce clotho, and movement releases irisin and BDNF. In her studies active 70-year-olds produced more longevity proteins than sedentary 35-year-olds.
How much extra life does Attia think his practices can add? Show answer
Perhaps ten years. He says he has far more agency over the quality of those years, especially his relationships.
