  3. Yay! I feel like I can make a contribution because I just came back from Venice. The word “Quaratine” came from the Italian for 40 – quaranta because, as you mentioned, this is how long the ships were required to stay in isolation before unloading cargo and passengers. Love your number research (but 34 is STILL my favorite ;))

  5. All I can say is this is one impressive list, Frank! You’ve added and calculated elements that go way over my head! You know your stuff! And my contribution to 40 is that this month my youngest child turns 40. Now THAT is sobering! 🙂 Thanks for ABBA–a favorite anytime!

      Many thanks … gathering the facts is easy, but can be time consuming … organizing them is the important challenge. Glad you enjoyed Abba … and Happy 40th to your youngest!

  7. Happy 40th Anniversary Frank! I don’t know if “40 is the new 20” logic applies to marriages or not but here’s hoping for many more regardless of the calculation. Opening Day went to the Phils…but if the Reds could have gotten one or two key hits the game certainly could have gone the other way. I’ve always hated the “day off” following openers that baseball loves to schedule but in this case it does mean the Phils will be undefeated for at least another day.

    • Bruce,
      Thanks for the anniversary wishes … and doing a numbers post is a way I celebrate. 🙂

      I didn’t make it to Opening Day as we made the mistake of trusting the weather reports. … Of course it didn’t rain a drop during the festivities we wanted to attend.

      Hitting with RISP has been a Reds bugaboo for 10+ years, and if the opener is a sign of things to come, the trend continues. The young Phillies need to stay the course!

      Although the Reds no longer open the season for the league, at least MLB lets the tradition of them opening at home continue … which also means the next day is an off day. (I’ve never liked that.)
