I do try very hard (honestly) but find insufferable (undeserved) smug does creep in

Well at my advanced age, there's a great need to give my brain a lot of exercise. You're not quite so ancient so all you need to do is just keep it ticking over. Smug comes before a fall.

I find cycling is useful and I work as well , I go to the office one day a week and work from home each day , I can see with my relatives none of whom work that they have become doo lally

Work provides the discipline but once you can no longer work, you have to go back to self-discipline.

Evening Adders,

As usual you are correct , I appear to have very little imagination and 40+ years in the Army gave me the discipline you speak about ,now that is over I need to work to give me challenges the other challenges were why I was sitting here and not there , why I was sitting when I should be standing and why I had not done this and done that (WIFE) and that would end up with one or both of us behind bars

;-) Like it!!

"Zodiac killings"

I guess it's possible that they've IDed the perp, but he's dead and the evidence wouldn't convict in a law court.

To go back to the 60s/70s and convict, you really need DNA evidence or a confession.

Police in the UK do retain evidence in unsolved cases, for ever.

The oldest case solved by DNA was a 1956 murder case in Montana. Unfortunately the man IDed had died, but the family voluntarily took DNA tests which proved their father was the killer.
