Now, I'm not trying to be rude to anyone here - BUT;
Why on earth would anyone over 60 want to keep working ?
Particulary in this environment which is so damaging to your health.
( Unless you've been unfortunate enought have a financial / family tragedy in recent years, it seems a sad way to spend your life)
One of the things you won't be saying to yourself on your death bed is "my, I wish I'd worked a few more days in my life"
