(1) Take a lot of rest, and
(2) Avoid smoky pubs.
I finished work early on Friday and went straight home without enjoying an end of-week pint. This morning I "rested" by lying on the sofa and reading some more of William Hague's biography of William Pitt. But what about the second instruction?
It suddenly dawned on me that the Scottish parliament's latest attack on property rights that came into force today must have been timed to coincide with my cold. So I went to the (non-smoky) pub and had a couple of pints.
Only following the doctor's orders.
