100th birthdays may soon be the norm

Life expectancy may balloon to 100 years old in rich nations thanks to scientific advances, but such progress could widen the gap between wealthy and poor nations, according to researchers.
Within the next 10 years, state-of-the-art, anti-ageing technologies could -- if they come into widespread use -- radically start altering global demographics, extending people's lifespans by 20 years, according to Shripad Tuljapurkar, a Stanford University biologist.
Tuljapurkar, in a study presented to the annual meeting of the The American Association for the Advancement of Science (AAAS), said such technologies could see people in industrialized countries living to age 100.
Aubrey De Gray, a biologist at Cambridge University in England, backed up Tuljapurkar's research.
"There is a 50 percent chance of creating therapies within 20 years to give middle-aged people an extra 25 years of life," De Gray said.
AFP reports: However, Tuljapurkar, who is also a professor of population studies, warned such advances could trigger critical social and socio-economic problems, creating a larger gap between the world's rich and poor.
He also questions how the world and policymakers would cope with a "longer-lived" population.
"Some people believe we are on the brink of being able to extend human lifespan significantly, because we've got most of the technologies we need to do it," Tuljapurkar said.
He estimated that between 2010 and 2030, the most common age of death will increase by 20 years if anti-ageing therapies come into wide use.
