Harman hypothesized that these compounds, which chemists call free radicals, react with cellular components, causing damage that over time leads to aging. In the 1970s he expanded on this theory ...

The results lend support to the free-radical theory of aging, which attributes many of the infirmities of old age to accumulated cellular damage caused by ROS and the free radicals they generate.

As they're looking around, free radicals can damage human cells. The consequences of that damage include effects like ...
