I'm a doctor who tracks my health. My 93-year-old dad does none of that.

Jessica Wu is a dermatologist who trained at Harvard Medical School.

Her dad, 93, incorporates movement into his daily life, eats light, and prioritizes social connection.

Watching him has influenced how she talks about health with her patients, she says.

This as-told-to essay is based on a conversation with dermatologist Dr.

Jessica Wu .

It has been edited for length and clarity .

My dad has never tracked his sleep , and wouldn't know what a macro is.

He has never set foot in a gym, and doesn't own sneakers (he prefers loafers).

And yet, at 93, he continues to live a healthy, fulfilling life.

His habits are small and simple.
