First, so sorry to hear about your health problems. Best of luck on all that.
As to the retirement issue, I do suspect that it will drive some of us out of the business earlier than otherwise might be expected.
Trying to be positive, we've weathered big changes before, and eventually adjusted. I remember TRA 86, OBRA, GATT, EGTRRA, etc., etc. - there were a lot of changes over the years, and we managed to adjust. But this has so much more stupidity, and I'm a lot older and less enthusiastic about work these days!
