I think there must be more of (us) there than we all realise. I mean, brothers reaching out is at an all time low, information via the internet is at an all time high and the preaching work has now become a motionless, speechless babysitting of a book shelf advertising a website as someone here pointed out!
Way back when I had similar thoughts, and my theory was that I can identify those by their behavior, which was similar to mine. Those that constantly find an excuse to get out, walk around, always have some kind of something to take care of, those who always volunteer to do work that keeps them away from sitting all day.
Never had the chance to prove my theory, but I think some behaviors are telling.
