As a medical school professor, I teach that aging is not just about time. It's about biology.

A new randomized clinical trial from Harvard and Mass General Brigham found that a daily multivitamin slowed biological aging by about 4 months over just 2 years. The study, published in Nature Medicine, used five different epigenetic clocks to measure DNA changes in 958 older adults.

The group that benef...

I taught medical students about every risk factor for aging — smoking, obesity, blood pressure, blood sugar.

I never once mentioned toxic relationships.

A new PNAS study of 2,345 adults found that each additional negative social tie ("hassler") was linked to a 1.5% faster pace of biological aging — and roughly 9 months of additional epigenetic age.

They measured this using DunedinPACE and GrimAge2 — the m...

Lifelong Social Connections Are Linked to Slower Biological Aging

A recent study by researchers at Cornell University shows that lifelong social support can slow biological aging. Using DNA-based epigenetic clocks, including GrimAge and DunedinPACE, scientists found that individuals with richer and more sustained social relationships exhibited younger biological p...
