Deliberately breathing in a radioactive mist and then looking at the pretty pictures the airflow makes in one’s lungs sounds like something libertines might try at some fin-de-siecle drunken bash. But that is just one of the tests I undertook during my recent stay in hospital. Then, to add to the jollity, they inject more radioactive material into your veins and watch the blood flow. On each occasion you have to lie in an awkward position for 15 minutes while the scanning machine moves slowly around your chest.
Modern medicine is a marvelous but sometimes scary business.
