In Chevy Chase, Md., Betty and Jack O’Connor are part of a growing number of people banding together to help each other grow old at home. Betty is 80, Jack, 85, and it’s something of a triumph that they’re still living independently in their suburban house, with its backyard garden and pool. Jack suffered a brain injury in a fall five years ago. Since then, a hip replacement has left him frail, and an allergic reaction to the anesthesia in that operation stole even more of his memory.
