My son Brandon sent me this link on Monday. It is of a lecture given by a Professor of Computer Science at Carnegie Mellon University. (I must warn you, you may need tissues). I think this is a must watch for everyone.
After watching the video, I wanted to know how he was doing, sadly he passed away on July 25th.
He aslo did a four part interview with Diane Sawyer, here is the link to the first part if you'd like to watch.
My heart goes out to his family, I hope you will include them in your prayers.
