    How to Foster the Flow State

    May 26, 2016

    In the last article, I explained what flow is and why it can be such a positive state. In this second part, I will summarise the best practical techniques to promote it, drawn from the works of psychology theory and research. These include a myriad of ways in which to structure the external environment as well as one’s inner world.


    Intermittent Fasting for a longer and healthier life

    May 25, 2016

    Our modern lifestyles are slowly killing us: by overeating and being excessively sedentary, we might have brought upon ourselves an epidemic in metabolic diseases. Our body is not optimized for these modern ways of life and we can’t change that overnight, nor even in the course of a few generations. Evolution is slow.

    Throughout evolution, the survival of humans may have greatly depended on the constraints of needing to acquire food. Food deprivation was most likely one of the biggest energetic and evolutionary challenges to our bodies - it is likely that many of our ancestors could only acquire food during daytime, having to fast for long hours; it is also likely that long periods of food scarcity were common. So, those who were able to endure in these conditions ended up being favoured by evolution.

    The fact that our bodies store fat as a backup long-term, high-energy source, and that we can survive relying solely on it for a fair amount of time, is an indication of how human evolution prepared us (and maybe even optimized us) to go through periods of fasting.
