We know that once we stop learning and call ourselves learned, we become useless members of the scientific society.

The war broke out, and for a number of years I lived in darkness, with the memory of the lakes, the trees and the skies of Sweden, until I returned in 1946 to spend two unforgettable years in the laboratory of Hugo Theorell.

Due to these various circumstances, when I entered the Catholic University of Louvain in 1934, I had already travelled in a number of European countries and spoke four languages fairly fluently. This turned out to be a valuable asset in my subsequent career as a scientist.

Although attracted by the humanities, I had chosen medicine as a career, seduced by the image of the 'man in white' dispensing care and solace to the suffering. But science was lurking around the corner, in the form of an unpaid student assistantship in the laboratory of physiology.

As we continue to fight the War on Terror, it is imperative that we protect America's fallen heroes by ensuring that they are treated with respect, while being laid to rest.

We have an obligation and a responsibility to be investing in our students and our schools. We must make sure that people who have the grades, the desire and the will, but not the money, can still get the best education possible.

Every country in every war fights for freedom.

Instead of a national curriculum for education, what is really needed is an individual curriculum for every child.
