I'll be very brief. I'm not a tax accountant at all. I'm aware of the debate around the issue you're suggesting there. I really am aware of that, and I apologize; sorry.
I would just point out very quickly that I'm not sure that those forecasts would in fact unfold in that way—that is to say, that there would be a mass rush and that people would go at a certain point. I'm just thinking about universal retirement. Mandatory retirement for professors was taken out about five years ago. People predicted that there would be huge numbers of professors working well into their 70s and 80s. The averages haven't changed at all.
