Since one doctor said it is impossible and you're out of luck if you lose both legs at once do you know people who learned to use two prosthetic legs simultaneously?

Do I, PERSONALLY, know someone with two artificial legs? No. But Oscar Pistorius of South Africa just barely missed qualifying for the Beijing Olympics as a runner, despite having two artificial legs. And don't tell the Marines who ran with President Bush after losing both legs to IEDs in Iraq a couple of years ago.

Ten years ago, that doctor might have been right. Now he's completely wrong. The technology for prosthetic limbs has made ENORMOUS strides in the last five years, thanks in part to new materials and the explosive development in computers.
