Modern technology makes the world into a global village. I just found out that an old friend of mine from yeshiva suddenly passed away. I hadn't heard about him in about 30 years and then suddenly - BOOM - gone from this world.
This is of course a huuuuge tragedy [he left a wife plus 5]. It also makes me wonder when my turn is. I don't know but I DO know that I also have a "due date" and better get my act together. What can really shake a person is the knowledge that no person on earth can guarantee that he or she will be alive in ONE SECOND from now.
The most important thing to remember is to spread love.
