i have many chums who don’t do anything at all now that they’re retired. Beyond the daily crossword in the paper, and watching the daytime tv lifestyle programmes, they don’t do anything else to keep their brains active. Other friends belong to the U3A organisation – our local one is very active by all accounts and encourage all members to follow up lectures with online training and refresher materials. It’s very obvious which set of friends do this – they are so much more lively to talk t and can remember everything about a subject – it will have been embedded in their brains and kept them from rapidly losing their capacity to recall and repeat. The vast array of online courses is staggering – we’ve never had such an amazing choice as now and the idea that oldies can keep surfing for ever is very comforting to me!
