I suppose we all get tarred with the same brush, just because some older people are too stuck in their beliefs and don't bother to keep learning. I once said to my ex-FiL that I learnt so much from my daughter, and he said 'the day I think a 21 year old knows more than me I will shoot myself'.
When we are very young we have a very small world, and we know what we need to in order to survive. That world expands hugely as young adults and we learn all sorts of things. Then somehow we seem to have had enough of it as we age, and retreat again and shut our minds and ears to what is going on in the wider world. Of course, so much is going on that we can't possibly keep up with it all, but my own mother seems to live in a teeny sheltered bubble of her own, compared to a village friend I have of the same age (79) who is amazingly tolerant and well-informed. My mother is still convinced that she will get piles if she sits on cold ground! Along with too many other old wives' tales to mention.
