Soccer: fast lane to dementia?

When I was 8 years old I would ferociously head heavy old leather soccer balls to the point of getting the nickname "Bullethead Smith", and this continued on as I was playing in central defense throughout my teens. After that the balls became lighter, I would say, and nowadays when I head a ball there is no shock whatsoever. But, as that fish in the restaurant aquarium tank in the Monty Python movie "Meaning of Life" said, when it saw its friend being eaten, reports like this "make you sort of think, don't they"?

Just wonderful

It was just wonderful to welcome my ex-boss, Martin Karplus to ORNL for the Wigner Lecture the 25th birthday celebrations of the ORNL Leadership Computing Facility last week.

87 years old, but still unbelievably sharp, and still working hard, he is still asking important questions in his research.

In my opinion he is among the most accomplished of the Nobel Laureates.
