Researchers find link between aging and chemicals in environment

Why are some 75-year-olds downright spry while others can barely get around? Part of the explanation, say researchers writing in the Cell Press journal Trends in Molecular Medicine on May 28, is differences from one person to the next in exposure to harmful substances in the environment, chemicals such as benzene, cigarette smoke, and even stress.
