An old man in a nursing home was described as being depressed, unresponsive and "un-alive"...but wait until you see him "come to life" when he hears music from his era. After his caretaker puts the headphones on him and flips on an iPod, you can actually see the pure joy on his face. So awesome.
He starts listening to music around the 2:15 mark of the video. It's a long video but it's totally worth it to see our beloved technology tapping into nostalgia for what seems to be a really rad old guy.
