Older adults buddy up with Amazon's Alexa

When Willie Kate Friar wakes in the middle of the night, the octogenarian doesn't have to turn on the lights or crane her neck to find out the time. She simply asks her digital assistant, who responds in a life-like voice. "I've found Alexa is like a companion," Friar said of Amazon Echo's new voice-controlled assistant, a black cylinder called Alexa. A Panama-based retiree who writes and lectures on cruise boats, Friar is recuperating from a recent fall and asks Alexa to play music during her physical therapy sessions. "The music lifts my spirits," she said.
