Hanco: I had to think hard to come up with a regret of any kind.
The only thing that comes close is I do sort of wish I had retired from my police career at age 46 (25 years service) instead of going for the more lucrative retirement with 30 years service.
I broke my leg/knee in my 29th year and that, on duty injury, causes me to receive a duty related medical pension that "sadly" is TAX FREE and based on 29 years service!
I would rather have a natural knee instead of this titanium one and would gladly pay the income taxes were that to be possible - but its not, so C'est la vie!
Living with no regrets (clear conscience!) is a good and low stress thing - I am blessed.
