https://en.wikipedia.org/wiki/John_Cazale March 13, 1978. Forty years ago. This excellent character actor in what should have been the middle of a long career died of lung cancer. He was 42 years old. You might recognize him as Fredo Corleone, brother of Michael (Al Pacino) from The Godfather (I and II). He partnered up with Al Pacino again in Dog Day Afternoon, and was in The Deer Hunter with Robert DeNiro. Life is short. His was too short by about 40 years. So, the lesson is to be thankful for our life, and treat our health and well-being seriously, because you can't take it for granted.
