Not so much the year, so much as passing 50 years old a fortnight ago. I received three vital pieces of advice for the future:

1. Never waste an erection;
2. Never trust a fart;
3. Er ... we've forgotten.

Having also restarted my career in the last few months, I can offer some advice. Knowledge is never obsolete, skills are never lost and redundancy might be defeat but never disgrace.
