Well I'm 50 and my job involves a lot of context shifting, solving sudden problems with systems I'm not an expert at (thus requiring research) and generally being a jack of all trades. I find it easier to do now than I did when I was younger, I see it as just what the job is. When I was younger, a sudden demand to do something different would have me annoyed because it was distracting me from what I really wanted to be working on. Now I know that everything will be different in 5 or 10 years, so it doesn't really matter what I'm working on as it will be irrelevant soon.
