Another Space Milestone for John Glenn

(NAPS) When John Glenn became the first American to orbit the Earth in 1962 he probably never imagined that decades later he'd also become America's first senior citizen astronaut.

But in October, at 77 years of age, he'll return to the "final frontier" aboard the space shuttle Discovery.

And that's not the only frontier John Glenn is talking about these days. "In the next fifty years, the number of people over 65 will triple. Research on aging is essential to preventing or delaying diseases like Alzheimer's, diabetes and osteoporosis," said Senator Glenn in a new television public service announcement for the American Federation for Aging Research. "The support of aging research will ensure that older Americans remain vital, productive and independent."
