Document Summary
Review: over long-term, negative health effects (ex: aging, heart & immune problems) Stress also affects health indirectly through behavioral (ex: bad eating, sleep, etc) 3 health-related dimensions: commitment, control, challenge, more effective problem solvers. How 3 affect health?

After 6 weeks, filled out anxiety, tension scale. Vigorous group had less tension (compared to time 1 and moderate group) People rated recent evens (stressful) life events and fitness. Kept records of health for next 9 months. Results: low fit under stress had poorer health. But stress had little impact on health of high fit.

Recall: telomeres: in most cells, telomeres shrink with each cell division. Reported daily minutes of vigorous activity for 3 days. Studies show better response to stress, even longevity.
