As we age, our cells get "rusty" and weak, which leads to diseases and disabilities. Current medicine only treats the symptoms, not the actual aging of the cells. Altos Labs is creating a "reset button" for cells. By using a scientific trick, they can make old, tired cells act young and healthy again without changing what they do. People can enjoy a much longer "healthspan." This means staying active, sharp, and free from disease deep into old age, turning 90 into the new 50.
