A post to the effect that previously only Toffs (yes we are in the age of Toffs) could afford to buy books and now only Toffs can afford to read them. Nice one Quentin! But I might take issue with you over this one. Mrs Brown packed a few volumes in and I, a poor and lowly thing, have managed to squeeze a few tomes for nurture.
You may know already, but if you do not, ambulance persons use the term Tof. It may not be proper or correct, however, it identifies the condition where an older person falls over and sustains a fracture to the top of the femur. As an older person who recently sustained a fall in the sobriety of the early afternoon I was reassured, on a number of counts, I was not a Tof.
In addition!
So that is what Dave Mackay looks like.
One of the books you should read is:-
David J.C. MacKay. Sustainable Energy – without the hot air.
UIT Cambridge, 2008. ISBN 978-0-9544529-3-3.
Available free online from www.withouthotair.com.
So it won't cost you anything but the time! You can't afford not to!
