He was never a defeatist; he was always death ended an active life of scientiﬁc inquiry and hopeful, no matter how serious or complicated the accomplishment. His searching mind and the ready applica- Elizabeth Bunnell, and a son, Sterling Bunnell, Jr. Bunnell stressed the same sound principles of surgery he practiced himself and was critical if his student failed to rise to this standard. As a result, he has left us not only the fruits of his labors in the way of scientiﬁc accomplishment, but also the in- spiration that he so dynamically displayed during his lifetime. Through his efforts, surgery of the hand has been nourished and developed to the state of worldwide recognition it enjoys today. The acceptance of his scientiﬁc and surgical accomplishments came early, both in the United States and abroad, as evidenced by society mem- berships and awards. He was a licentiate of the American Boards of General, Plastic, and Ortho- pedic Surgery. He was an honorary member of the American Orthopedic Association, the American Academy of Orthopedic Surgeons, the Western Orthopedic Association, the California Society of Plastic Surgeons, the Societal Latino-Americana Sir Stanford CADE de Ortopedia y Traumatologia, an honorary fellow of the British Orthopedic Association, 1895–1973 and a foreign corresponding member of the Societas Ortopedica Scandinavica.

It may seem perverse to criticise a campaign to encourage people to take more exercise buy 20 mg paroxetine free shipping, something that many would regard as self- evidently beneficial 30mg paroxetine free shipping. Yet it is important to note the subtly coercive character of these exercise programmes. As a doctor, I do not advise or recommend exercise, but I prescribe it, in the same manner as I would a drug or other medical treatment. As the programme leaflet indicates, ‘an exercise prescription is similar to a prescription for medicine issued by your GP…in many cases exercise can help to control certain medical conditions and in some cases reduce the need for medication’. The deliberate use of the term ‘prescription’ implies an expectation that the patient will follow the doctor’s instructions to turn up at the gym, just as they would be expected to take a traditional prescription to the pharmacy and take the medication in the manner prescribed: ‘all patients should be made aware of the fact that the prescription is an important part of their treatment’. Issuing a prescripton to take exercise clearly imposes a much greater pressure for compliance on the patient than there would be if the doctor merely advised exercise. In the past, they have often warned of the dangers of particular sports and have complained about the burden on accident and emergency and orthopaedic departments resulting from sports injuries. In 1990 the BMA published a detailed account of the dangers of sporting and leisure activities, noting 155 fatalities in 1987, including some 61 drownings in various water sports, 24 deaths from parachuting, hang-gliding and other forms of aerial recreation, 12 from horse-riding and jumping (though only one in boxing, the target of a continuing medical campaign) (BMA 1990: 147–8). The growing popularity of more dangerous sports, like mountain climbing and off-piste skiing, has led to an increase in sport-related mortality, despite the increasing preoccupation with safety. Two factors have converged to make exercise a key feature of the modern health promotion agenda. One is the burgeoning cult of the body that has become a central theme of Western society over the past twenty years. This began with the vogue for jogging and marathon running in the 1970s and 1980s and has flourished in the form of gym-based fitness training in the 1990s. People seem to have forgotten that Pheidippides, the runner of the first marathon in 490 BC, collapsed and died on reaching Athens—and that James Fixx, who popularised jogging in the USA with his 1977 best-seller, dropped dead on the track in 1984 at the age of 52 (Skrabanek 1994:74–5). The second factor is the increasing medical promotion of the preventive value of exercise in relation to a wide range of health problems, from coronary heart disease and osteoporosis, to depression and anxiety. In 1991 the Royal College of Physicians reviewed the medical aspects of exercise, balanced the benefits and risks and pronounced that regular exercise conferred definite ‘physical and psychosocial benefits’ (RCP 1991).
