I'm beginning to think the "eventualy move into management" when you get to your mid to late 30's is just the normal development path in IT. I'm desperately trying to avoid it, myself, but as I get older I constantly find management jobs being thrust in my direction.
That's working the private sector, of course. In the public sector, there was nothing to worry about, since nobody ever seemed to retire -- I could've stayed a programmer well into my 50's.
The alternative is to learn some skill that never seems to be fall out of use -- I see tons of graybeards in my company that do nothing but maintain aging AS400 and larger mainframe systems all day.
Honestly, they seem to be the happiest of the bunch...
