Go see Star Wars, Revenge of the Sith.
Sit down in the theater and look around. Maybe strike up a conversation with the person next to you.
In a few moments you will realize that over half the people in the theater weren’t even born when the first Star Wars came out in 1977. Yep, Luke, Han, Lea and the gang romped around the galaxy 28 that’s TWENTY EIGHT years ago.
That’s over a generation in time.
