I went for a drink with an Elder in his early 30's a few weeks back and although he respected my wish not to go into why I no longer attended he just had to mention all the great changes which are happening because we're sooo close to the end. He's a bright lad as well, but just a bit potty for the org.
Then just yesterday I got talking to an ex Elder (he stepped down years ago due to mental health issues) and although being all about 'The Truth' he did say he couldn't go on much longer and longs for the new system. He's in in late 40's now, so from my experience it is ones in this group upwards that are feeling the strain of not getting what was promised by the GB.
Oh and I just remembered overhearing a group of older ladies in their 70's joking yet serious, about how they didn't think they would see 70 in this system of things!!! CD at its finest.
