In the last 24 months in a cong of 100 pubs (but 75-80 average meeting attendance), we have had 2 df'd and a family of 4 fade.
It also has about 5 very old ones who will no doubt 'stop' attending within the next 12 months, and quite a few other old ones who are finding it more and more difficult.
Two elders fall into that latter category and have had their responsibilities lightened because they can no longer do all the required stuff.
