The UK Independent carries an article which claims the first person who will live to 150 has probably already been born. On people who have already lived to advanced ages the article says:
Jeanne Calment died peacefully in a nursing home in Arles, southern France in 1998. She was aged 122 years, five months and 14 days - and no one has yet challenged her title as the oldest person with an authenticated birth record to have lived. She attributed her longevity to a diet rich in olive oil, regular glasses of port and her ability to "keep smiling".
