calmck I don't agree. Most of the knowledge (not all obviously) accrued by over 75's is outdated. I find younger people know far more than I did at their age and are on the whole more inclusive, less racist and more concerned about their future than we ever were. The 'Good Old Days' when examined without rose coloured specs, are far less appealing.
JOrdy, you are as usual, very astute in your observations and obviously have all, if not most, of your marbles left to play with lol! x
