I know how you feel! After 30 years of working in residential construction and a tired back I've gone back to college to get up to speed with the electronic age. Don't fret,the kids may be fast at the keyboard but the knowlege gained through experience has a greater value.Present yourself with " I not only know how , I also know why"
Good luck Fred. I know you are the best man for the job. Good things also happen to good people. So, if things don't work out there (but hopefully they do), it probably just means something better for you is just around the corner.
