The science of a long life

Bombarded with adverts promising a longer, healthier life, BBC News Los Angeles correspondent Peter Bowes goes in search of eternal youth.
If we are lucky, we will grow old. Most of us have grey hair, wrinkles, frailty, loss of memory and degenerative diseases to look forward to - if we do not have them already. It is not all bad news. With ageing, we can acquire wisdom and often become more emotionally stable and at ease with life. But the downsides seem to far outweigh the perks. We live in a youth-oriented world.
California epitomises a society where everyone wants to be young, attractive and vibrant. Being old, looking old, acting old is not an option, so much so that after many years operating as the University of California's Ageing Centre, in Los Angeles, the name was changed to Longevity Center, to "give it a more positive spin," according to its director, Dr Gary Small.
