Or as a Chinese Proverb says "A single conversation with a wise, aged and experienced man is better than ten years of study with a young man."
I think that's precisely the sort of thinking that HQ was questioning - the Chinese culturally have a far greater respect of their elders than we in the West do; yet in actual fact, the elders are not as full of the wisdom as that proverb implies.
Either way, you can't have it both ways: you started out by saying that age shouldn't have anything to do with, and then went onto say that '
In fact if you look at the record - with probably a few exceptions - our best achievements where achieved under an older person'.
I would question the extent to which that is actually true. You might think that Blair cocked up the country, but that's arguably a political opinion, and not a careful analysis of his performance in the modern role of PM. And while both Thatcher and Attlee were undoubtedly the greatest PMs since WWII, that wasn't necessarily because of their age. In fact, your Churchill example works against you, there: his second term of office was a notable failure when - in theory - he was "older and wiser", as the saying puts it.
The reality is that it's only been in very recent times that someone in their forties would be seriously considered for the post of party leader in the UK. In the times of Thatcher, and before, you had to be an older person. So by definition, great leaders of the past are going to be older.
And then there are the counter examples, starting with Alexander the Great, Alfred the Great, Ludwig Wittgenstein, Karl Marx, Voltaire, Pitt the Younger, Albert Einstein, all of whom had acheived their reputations, or important insights, etc., before the age of 40.
You were right first time: age is not necessarily a factor.
