Most of our lifetime is spent in repetitive, routine activity. Yet interesting. In fact, even the most menial task might teach us something, if seen with a sciency eye. Washing dishes stimulates interesting thoughts on movement, fluid dynamic and surface chemistry. While walking, we can select a channel (i.e., only vision or low-pitch noise) to explore part of the spectrum we do not often think of. Being in a crowd or a noisy environment forces us to perceive the difference between the single object/person and the crowd itself.
What is the goal of this exercises? Maximize the objective function with respect to happiness, while stimulating active cognitive process in our mind and body. I am going for a walk 🙂
