Quoted context

These are the quoted author’s words.

Slowing aging by just one year would add ~$400B per year to U.S. GDP. Slowing it by five years would add $2T - more than twice the annual U.S. defense budget. In 2024, the U.S. federal government spent roughly $2.6T on Social Security and Medicare (about 38% of total federal spending), and most of it was concentrated on older adults 65+. By 2029, this spending will grow to $3T every year. This structural and fiscal pressure of aging creates economic opportunity where even a small shift in biological aging could be transformative.
