My Memory Tags

I was in the car with my wife, and we were trying to determine how old one of her nephews was (she has 14 neices and nephews, so it’s harder than it seems).  It turned out I remembered how old he was, because I knew I missed his Baptism because I was at a Rockets’ playoff game.  It occured to me that many of the things I remember are tied to sports.  I can remember when something happened based on what game I watched that week.  I’m wondering if that means I watch too much sports, or that is a condition of memory.
