My parents are late 70’s, very active. My Dad is due to retire shortly.
He exercises, which is good but I’m wondering what he can do to keep his rather clever brain active.
Is there anything anyone can recommend. He and Mum are very different in that she’s happy to stay in, odd lunch out, garden centre or shopping visit. So whilst they will do things together, me and my siblings feel he needs something a bit more to stay mentally active.
Someone suggested crosswords and sudoku but there are only so many of those you can do. Would really appreciate some suggestions, thanks
