That is a good time of life to work with teens, you are not too old to relate to their problems and their likes and dislikes. I'm 60 now and it is hard for me to even understand their language or to relate to the things that they are going through. I'm having fun teaching them how we did it in the old days though, and you know what, it's new and fresh to them now and they seem to like it. You know that I'm a cool guy too for my age lol, I'm not a complete stick in the mud like the older generation that they are used to, and I'm not a complete idiot when it comes to technology so that helps also.
