missing the agegroups

I have recently read a poston a blog which referred to an article in a magazine by the Methodist Church which suggested we have lost the ability to relate and reach those under the age of 45. It is certainly true that the age group from 20-45 i certainly missing in a number of our churches, but why is this, and do we need to change anything about our churches? One thing I will throw out there as a thought, and I will come back to this idea again, is that maybe the way we teach is different to the way people learn. The idea of sitting sitll and listening to someone talk for 20-30 minutes or longer, is somewhat strange to maybe those are missing from our churches. If we are really and truly going to reach a new generation, then maybe one thing to do is to change the way we get our message across.
