My, admittedly simplistic, understanding of why we age is that there are two factors at work. First, DNA gets corrupted as our cells divide. This leads to cancer. Secondly, in an effort to prevent cancer, cells divide slower and slower as we age, leading to slower regeneration. If we can somehow solve cancer, we could use telomerase to encourage cells to divide faster.
