Longevity & AgingTargeting Aging Itself Could Prevent Every Major Age-Related Disease at Once
Geroscience is shifting medicine's focus from treating diseases like diabetes, Alzheimer's, and heart disease one by one to targeting the aging process that drives them all. Dr Nir Barzilai, who has spent decades studying centenarians, argues that people who reach 100 often delay disease for years through biological advantages we may be able to replicate. Existing drugs like metformin, SGLT2 inhibitors, and GLP-1 agonists already show broad anti-aging effects across multiple conditions simultaneously. The goal is not just longer life but a compressed period of illness — staying healthy longer and declining faster only at the very end. Barzilai believes the field is on the verge of making aging a genuinely modifiable process.
