I've been having a light brain fog for as long as I can remember.
There is an apparent feeling of being in motion. Attending meetings, working on my thesis etc. But in a way, it just feels like there is some 'doing', but not so much reflection or self awareness about why I am doing what I am doing.
In this struggle to reflect and think with clarity, I was inspired by walking itself as a thinking tool. Fascinatingly, walking has been utilised differently by different thinkers of different eras.
It helped Thoreau cope with his seclusion. For Rimbald, walking was a medium to vent his fury.
[Freidrich Wilhelm Nietzsche 1](Freidrich%20Wilhelm%20Nietzsche%201.md) used to carry a pocket notebook while walking and used to jot down ideas into what became his masterpiece — Thus Spake Zarathustra. [Nassim Taleb](Nassim%20Taleb.md) used to do 'rational flaneuring' —walking without purpose or a destination, even. Even Socrates used to be this 'walking philosopher' conducting philosophical and scientific enquiries while on the 'peripatoi' (walkways).
I have to say that I have also been heading for runs everyday, but I wouldn't term running as a thinking tool, as much as what walking is. The pace of your run is sometimes faster than your thought process.
To let one's thoughts ruminate, it has to match your own pace. Fortunately Ray Bradbury in his book Fahrenheit 451 describes this phenomenon in better words on how disastrous running or driving could be for thinking.

Running is a blur. And sometimes, we do need some Nietzschean walks!
I've been casually checking up on my daily walks using Apple Health. Nowadays, it's been on an all-time-high!
