How chronic stress is harming our DNA. Elissa Epel is studying how personality, stress processes and environment affect our DNA â and how we might lessen damaging effects.

A study just out shows that as we get older, our DNA changes. A lot. Researchers in Iceland and the U.S. showed that over a period of 10-16 years, some people's DNA changed as much as 20%.
