I've already explained some of the personal meaning this number has to me, but I also wanted to throw out some facts about the number. Including all the great athletes that have worn it.
There are a ton of interesting facts here, but I just wanted to pick out a few. Diecinueve is the 8th smallest prime number. XIX is also the atomic number of potassium. I just read that the New General Catalogue object NGC19 is a barred spiral galaxy in the constellation Andromeda. Interesting enough, my initials are NGC. I'm going to have to look into this a little more sometime.
Among the great athletes to wear this number are Tony Gwynn, Robin Yount, Bob Feller, Joe Montana, Johnny Unitas, Lance Alworth, Bernie Kosar, Willis Reed (NBA), Lenny Wilkens(NBA), Don Nelson (NBA). And more recently Keyshawn Johnson, Michael Bush (Louisville Runningback), Lionel Messi (international soccer player-Barcelona & Argentina). Some of my personal favorites are Juan Gonzalez and Robin Ventura.
Just incase you didn't figure it out the number was 19.
