A new study out of University of California, Irvine suggests that the Sept. 11 attacks made Americans more sickly.

Researchers contend that in the first three years following the attacks, reports of doctor-diagnosed illness jumped 18 percent.

Those who watched the attacks on TV had an even higher incident rate.

Experts say large-scale collective traumas trigger stressful events that may weaken immune systems and make us more susceptible to illnesses.
