Our grandchildren are discussing what subjects to take at GCSE. It got us into talking about life-long learning and changes in our lives. Think, for example, of the world-wide web ; the shrinkage of religious influence in the UK; the impact of social media; Brexit, covid 19; your own ageing.  Clearly choosing which [academic] subjects to learn affects job chances and life-interests – as it did for us.  But a key to education and living lies in understanding ‘how’ you yourself best learn.  And for all of us there is the personal task of sustaining our passions and commitments whilst being open to new ventures.  In all of it, as has been said so often, we each have to work at adapting and making changes.  Some would say the large issues today are - wars and conflict, disease and covid, climate change and water shortage, the whole financial system: somehow humans have to sort them together.
