Where is the light switch?

I have just been reading the article about the Diaconnal Convocation in the Methodist Recorder. Richard Vautrey was saying that there was so much creativity in worship and outreach and yet a study said that the Methodist Church had 37 years left before the lights would be switched off. I worked out that this would make me 66 and possibly thinking about retirement - do I need to start looking for the light switch??
