They say a little knowledge is a dangerous thing. They are completely wrong. We all have only a little knowledge. The dangerous thing is being satisfied with that.
I am now retired after teaching online with the OU since 2000. I now have more time for useful things like sorting my stamp collection. I do bits and pieces of work for the Liberal Democrats. I still mourn the loss of Lewes's best ever MP, Norman Baker. I am usually online for about ten hours a day, living in my airing cupboard much of the time. Despite this I have a healthy skin colour and do not lack for company.
