After 44 years in prison, Otis Johnson, a 69-year-old former prisoner is back in the society. He went to jail in 1975 at the age of 25, for assault and attempted murder of a police officer.

Today, he's confused, struck by the overwhelming number of people talking to themselves on iPhones and wires in their ears. He's fascinated by the way that the society was changed and how technology has changed people.

"I see that the majority of people were talking to themselves. Then I looked closely and they seemed to have things in their ears. I don't know the things, the phone things, iPhones they call them, or something like that. And I thought in my mind, what, everybody became CIA or agents or some stuff like that? Because that's the only thing I could think of, someone walking around with wires in their ears.. that's what they had when I was out during the 60s and 70s."

"I'm trying to figure out how people do that, control themselves to walk and talk on the phone without even looking where they're going," he said. "That was amazing to me."

Al Jazeera English camera crew featured Johnson and followed him around New York.
