The beautiful building where CWTS is housed is part of Leiden’s cultural heritage. It was the first physiological laboratory of the university, hence it is named after Willem Einthoven. In this area a couple of proud cocks roam the area, quite beautiful and confident animals.
Until recently, they had not seemed to respond storngly to people. However, the day before yesterday, as I approached, they immediately ran over and clearly expected me to feed them. It was the day of the opening of the academic year, so I guessed someone in a black suit (which I was wearing for the occasion) must have the habit of feeding them. As I left them, they seemed genuinely disappointed.
