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.

It is important to feel the anger without judging it, without attempting to find meaning in it. It may take many forms: anger at the health-care system, at life, at your loved one for leaving. Life is unfair. Death is unfair. Anger is a natural reaction to the unfairness of loss.

Diabetes can be successfully prevented and managed by a healthy lifestyle. When not managed, it can lead to severe organ damage and death.

Shallowness and ignorance have been our lot in the mass consumer societies we inhabit, where we were too distracted to act politically, apart from periodically deputing political elites to take life-and-death decisions on our behalf.

In order to speak about all and to all, one has to speak of what all know and of the reality common to us all. The sea, rains, necessity, desire, the struggle against death... these are things that unite us all.
