"In the morning, there is a peak of productivity around 10AM, then it decreases until lunch time. After lunch, it starts to increase with a peak around 4PM, then it starts to decrease from 4PM until 7PM. Then, again, starting from 8PM, I restart working and there is a gradual increase with a peak at 11PM."

I wondered too - but the only other post on that blog tells us he's a phd student, so it's a little less surprising - at least to me...

Yeah, and here's a link to their Google Scholar page [1]. It's not surprising at all for a PhD student (especially a full-time one) to be working those hours.

It's also not uncommon (about a third I believe) for PhD students to suffer from depressions and what not.

our society is sick.

I did Pomodoro for about 3 years while I was doing my PhD (UK type). It was a live saver for me as I came from a study system that had all the questions and answers given to you, so the requirement of sitting in my desk to 'do research' was completely alien to me. Before I adopted Pomodoro, I tended to procrastinate and distract a lot. Using Pomodoro I got to focus, and found a way to split what I was doing (reading papers, writing, thinking about my problem) in small bites.

Nowadays I wouldn't think in using it, because my current work requires me to be interrupted plenty of times a day. Pomodoro is terrible if your activities include interacting with other people. But for me it really worked.
