That's where being older can be either a curse or a benefit. If you can age but still retain the ability and desire to learn new things, you have the potential of possessing several assets newer workers don't have:
1) A sense of perspective. This problem may be bad, but you've likely seen worse.
2) More emotional maturity. The ability to deal with non-IT types and not lose your cool is invaluable.
3) Deeper troubleshooting senses. Familiar or not, if the device's optical drive doesn't work, you're not likely going to shout "Defrag!".
4) A grasp of the way computer systems in general work. Bits are bits. Directory systems are directory systems. Permissions are permissions. The implementations change, but if you're around long enough, you will have seen something like it before.
5) You've learned that specializing is great for the short term, but if you want to keep it up, that can be a real bear. A CCIE from 1999 won't still be a CCIE in 2009 unless they've been studying for the last decade. But that 1999 CCIE is likely a very good networking tech.
