Symptoms of an Age
In Georgian times, a crippling illness struck thousands of cider drinkers in the west of England, who found mysterious relief only by taking the waters at Bath Spa. In Victorian England, prostitutes, seen as carriers of venereal disease, were forcibly detained and treated in hospitals until they were considered unlikely to infect the male population - particularly the lower ranks of the Army and Royal Navy. Peter France introduces two stories which show how previous generations have dealt with the problem of lead pollution and a disease in its time as worrying as AIDS. Film editor STEVE RONAY

A series of films about the way we live now. Fly Me
Narrated by Eleanor Bron The public image is glamorous - warm smiles and crisp uniforms, good looks and faraway places. No wonder thousands of hopefuls apply each year to become air stewardesses or stewards.
What happens to the few who succeed?
Helen MacLeod , from
Dunfermline, and Neil Dover , from Durham, both aged 21, are two of the latest batch of 15 trainees to join British
Airways. They've hardly ever travelled before. Now there's a demanding six-week course and a lot to learn - how to put out fires and push people down chutes, how to deal with difficult passengers and flirtatious ones. What if there's a hijack - or a heart attack? How much are the duty frees in Japanese yen?
If they pass their tests, Helen and Neil can look forward to a nerve-racking fledgling flight on a 747. After that - the excitement, insecurity and hard physical work of being 'waiters in the sky'. Written by IAIN JOHNSTONE Research JEAN MACFARLANE
