If you stop and think about it, the world is changing at a breakneck pace.

Otis Johnson doesn't need to stop and think about it. He's reminded of it every single day.

Johnson spent 44 years in prison for trying to murder a police officer. He was locked away at 25 and re-emerged a free man at 69. What he saw left him shocked.

iPhones. Drinks that come in a rainbow variety of colors. Peanut butter and jelly -- in the same jar. There are so many things that simply didn't exist before he was incarcerated that we don't think twice about using.

Getting acclimated to the (new) world around him has not been an easy task and a pensive Johnson freely discussed how tough the transition has been. It'll definitely make you think.
