I thank my friend who sent me this video clip from a Harvard professor.
It is 90 seconds.
I hope you like it.
One reason I like this is because this professor is an "older" man speaking, still engaged, still willing to serve.
He has suffered a heart attack, cancer, and a stroke. None of that has stopped him from forging on with learning and teaching and traveling.
You can see at the end that permission is granted to pass this on as long as it is not edited.
Grateful for your visit,
