24 Viewers Too Old

Are the average viewers of 24 too old to talk about theories or speculate on what is going to happen next?  I know that I am not a faithful viewer, but I catch a show here and there and it is not enough to give my personal theory.

Now you ask why does this have anything to do with age.  Well, everyone that I talk to about 24 seems old to me.  Secondly, the water cooler discussions about 24 seem to have an older crowd as well.  Do younger people watch this show?  Or is this show quickly coming to an end?

Seven seasons is a long run - maybe this is the last one.
