I decided not to fly for one and half years. I (re)discovered the pleasures of train travel (visiting friends and colleagues on the way, the moving office experience, the feel of doing the right thing). At the end of the project I (provisionally) decided to fly at most once a year. Now I am thinking that I should define a cost/benefit analysis for my flights (still restricted them to one a year).

I also sold my car, became vegan, and have recently completed a winter tour of Europe by bike (sometimes by train) spreading with my body and my bike the message that we need to act boldly to mitigate climate change. Great experience. I visited universities, a PhD workshop, and conferences in five countries. I gave several presentations and worked intensively on two papers with visited colleagues. Cycling oxygenated my brain and cleared my thoughts. The papers made a real jump forward.
