Antiaging researcher Nir Barzilai wants to redefine the meaning of life extension: not simply more years, but more years of disease-free life, free of the suffering and expense of cancer, heart disease, dementia, and other scourges of old age. Barzilai calls it your “health span,” and he’s working to extend it by decades via an affordable generic drug currently in common use for diabetes. Science writer Sam Apple, writing for Wired, dives into the sometimes outlandish world of life extension and describes how one scientist hopes to make the dream reality for millions of Americans.
In this summary, you will learn
- Why metformin could become the United States’ first FDA-approved antiaging drug,
- How metformin could extend what researcher Nir Barzilai calls people’s “health span” and
- Why health-span extension offers greater benefits than life extension.
