There's no place like home: Builders design for elderly

Sixteen years of ups and downs took their toll on Sharon Hitchcock's knees.

As a bus driver for the Clinton County Regional Educational Service Agency, Hitchcock often had to help special needs students on and off the bus. That meant frequent trips up and down the stairs, and loading wheelchairs.

The physical wear already is showing. At 65, Hitchcock had back surgery six years ago, and, last month, she went through a knee-replacement operation. She has now had both knees replaced.
