Longevity & aging

Extend healthspan. Aging is the single largest driver of disease burden, and it is treatable.

Aging underlies cardiovascular disease, cancer, neurodegeneration, and frailty. Every human alive is affected. The hallmarks-of-aging framework (López-Otín et al.) gives discrete targets: senescent cell clearance, epigenetic reprogramming, stem cell exhaustion. Partial cellular reprogramming (Altos, Retro, NewLimit) and geroprotective drugs (rapamycin, metformin class) are in early trials. Utility delta is enormous: current median healthspan ~75 years, theoretical ceiling unknown and likely much higher.

The success vision · 30 years horizon

If we solve this, here is the world we get.

low

Before · today

Healthspan declines starting ~age 50. Aging treated as inevitable rather than as a disease. ~100M humans living with frailty-driven decline.

After · 30 years

Healthspan extended by 20+ years. Aging recognized as a treatable condition with FDA-approved interventions. 100→120-year healthy lifespan common in cohorts born after 2030.

Extending healthy human life is a core progress goal. Curing aging is as legitimate a target as curing any single disease.
