Re: Don't forget us oldsters! @AC
Sorry, parts of that comment did concentrate too much on young people. I agree that cross training is required as well, but I think that it was covered to a degree by the "training their own people" statement at the beginning of the comment.
I am in my mid '50s and do face the same problems you do, but I hope that my core skills will remain in demand long enough to see me through to retirement, but I am beginning to wonder.
