(CBS) - Too much strenuous exercise can be bad for your heart.

The authors of both studies stress regular exercise is still necessary for long-term health.
(CBS) - A common antidepressant might slow Alzheimer's disease. That's according to a new study at Washington University and the University of Pennsylvania.
