I mentioned Futurelearn on another post but thought I would give it its own post. I discovered these courses at the beginning of the year and so far have competed four (three were very good one was a bit iffy). They are totally free and cover a wide range of subjects. I'm about to start one called 'A History Of Royal Food And Feasting' - it's for a bit of fun really. Anyways, they are open to anyone/anywhere. There are a number that focus on nutrition, there is a very popular one on mindfulness. You learn lots from others on the course so if you like being on here you'll enjoy the method of learning!
