Congratulations.
I retired some years back and I have never been able to understand those who continue to work until old age and failing health blocks them.
Peter, don't forget that some of us have to keep working, as much as I would like to retire it's just not possible. All depends on the cards that one is dealt with and finding myself starting out again in my 50's after having been 'towelled' in a divorce I reckon I'll need to keep going until at least 70.
But good luck to those that can, most of those that I know that managed it early
deserved it!
