At my advanced age

, should I even bother with it?
My take on this question is that every Referee should advance as far as they are capable. If you're going to do this sport for any length of time, then challenging oneself to advance is something that I think should come naturally. Doing the younger teams is fun, but to me it's alot more fun to be challenged in a match - whether it's fitness because they can all run faster than me, whether it's awareness and anticipation of pay - because they all run faster than me, Mana managment - how I deal with the whiners, troublemakers, those just trying to get an advantage in the game.
In order to deal with the above, I've had to get training, other referees observations, get in better shape - because they all run faster than me, and develop a better understanding of the game. All of this makes the games more fun and enables me to deal with a challenging match or a U-8 game.
So the point is - if I want to do this and have fun - it just makes sense to me to challenge myself to be a better referee than I was before. One of the ways to do this is to work on my upgrade & go to the next level.
