Longer ago than I like to remember a neurology registrar was doing a lecture on epilepsy in the Clore lecture theatre in University College Hospital Medical School. He asked us to give him some causes of fits. Tony Davies (hi Tony!) and I were sitting  a few rows up from the front and he shouted out “exercise!” Puzzled looks. “Pardon?” said the registrar.

The sequel to our visit last week to the homes of China and Yetimwork, saw three of us setting off in a Bingham van to buy tarpaulin for a roof repair and some supplies for other individuals. An Ethiopian had found two pieces of tarpaulin on sale for 350 Birr each. However when two foreigners asked to buy them the stall holder first bumped up the price to 1400 Birr - well you can’t blame him for trying! There was a delay while he searched for the receipt book (almost nothing can be purchased here without a receipt).
