I have found over the years you get more call backs when you do not leave a message (caller ID) - which explains why we get 50 hang ups a day.
Leaving messages does take a lot of effort and time (which costs money) and yields very low results. Of course all of the uninsurables will call you back - that much is for sure.
Interesting... I hadn't thought of that aspect...
Unisurable's... aren't they all candidates for GI, no matter what...? (Life Ins). I guess for health this would be a different matter.
