Tech gadgets are being used in nursing homes to bring back the past, in order to improve the spirits of the elderly. From Gizmodo: "An old man in a nursing home is described as being depressed, unresponsive and 'un-alive' until he hears music from his era. When his caretaker puts the headphones on him and flips on the iPod, you can see the pure joy on his face. ... He starts listening to music around the 2:15 mark of the video. It's a long video but it's totally worth it, technology tapping into nostalgia." He remembers Cab Calloway and the 1943 popular song, I'll Be Home for Christmas.
