Yes, I think there are two issues:
a) It's harder to do certain jobs as you get older. My dp is in IT, and he says he finds it harder to grasp new stuff now he's in his 50s, and he'd like to "downsize" to a less demanding job as well. While experience is good and favours older workers, in many jobs there's always new stuff to learn, which favours younger people. Of course, for manual jobs, it's a similar issue.
b) It's harder to get a new job as you get older, as people don't want to employ you, even if you can do the work. Therefore, if you lose you job in your 50s, it's a real struggle.
TLT This was a government funded institute, rather than public sector, so perhaps straight public sector would be ok...
sportinguista Have you just turned 50?
I think that's when the age thing hits... It's when the recruiter sees O-levels not GCSEs.
