I have just discovered Future Learn which provides free online courses on many different topics, many of which would be of interest to us Gransnetters. Most of the courses last about 3 or four weeks. Here is a link to the list of courses; www.futurelearn.com/courses/upcoming
I have registered for the one about literature and mental health. I read avidly and write poetry, and have also suffered a depressive illness, so I hope to gain a lot from this.
There are courses of particular relevance to us on here: Successful Ageing, Religion and Conflict (this seems to be a hot topic here!), and health related topics; as well as astronomy, langauges and many others.
I have no idea how it is funded but intend to take the opportunities that it is offering. This may be of particular relevance to the OP who began the thread about how we do we fill our time.
I hope that you will find something of interest.
Is there such a thing as delicious ready meals?
Things you find stressful that other people don't notice.
How do you acknowledge Easter.
