Arthur Dent is not convinced when his best friend, Ford Prefect, tells him that the world is about to end in 12 minutes. Should he remain lying in front of the bulldozers intent on demolishing his house to make way for a bypass? Or should he accept the offer of rescue from Ford, who reveals that he is an alien from the planet of Betelgeuse (pronounced Bee-tle-jooce), and not from Guildford after all?

Second in a series of seven films about the source of human abilities.

'I can remember 50 years ago as if it was yesterday - but ask me what I did five weeks ago and I've no idea.' So says the late Stanley Holloway recalling his early days for this programme, and underlining the unpredictable nature of memory. A middle-aged man in California can remember his life before 1960, but virtually nothing since then. Aborigine children from the Australian bush have a staggering visual memory. A 'memory man' pits his wits against Ernie, the Premium Bond computer, in an investigation of the many strands of memory.

By unpicking the complex machinery of the brain which stores our memories, scientists are finding changes in the brain cells which may be permanent and are the first clues to the mystery of memory. Some day there may even be a medicine to cure forgetfulness.

To many thousands of gardeners, the Chelsea Flower Show is the finest living 'catalogue', full of dazzling colour, fragrance and innovation.
After a particularly hard winter that spectacle would not be possible without months of patient preparation and the years of experience behind each exhibit.
Peter Seabrook meets some of the growers, both on their nurseries and at the showground to find out just what goes into a display worthy of the Royal Horticultural Society's gold medal.

(Coverage of Chelsea Flower Show can be seen on Wednesday at 8.20 pm and heard earlier in the day on Gloria Hunniford's Radio 2 programme at 12.0)
