In 1949 he wrote an editorial on the future of medicine, aging, and longevity that wouldn’t seem out of place today.

These commentaries of past years, printed on paper, often vanish into the void. Fortunately this one remains.

Thus those of us who have advocated and raised funds for the rejuvenation biotechnology of today must have an argument as to why this decade is different, why
