Stephen Hawking is sick?

Mathematician Stephen Hawking rushed to hospital

Famed British mathematician Stephen Hawking has been rushed to a hospital and is very ill, his employer Cambridge University said Monday. Hawking had been expected to travel to Canada this year to act as a Research Chair at the University of Waterloo's Perimeter Institute.

UPDATE: Stephen is expected to recover. His example, and I don't just mean this slight setback, is like so many others that I'm trying hard to follow. It really is fantastic and inspiring. Individuals can make an enormous difference when they decide where and why to make it.
