At the front of a steep lecture hall, beneath two broad projection screens, Kimberly DuVall-Early was teaching 100 tightly wound college students how to chill out.
"We think, in our society, that we're supposed to do two or three things at a time," she said. "If you're washing the dishes, just wash the dishes, and focus on that. Go on the quad and just watch the squirrels. It's relaxing."
DuVall-Early's lectures about stress, memory and aging hold students in thrall.
