I have a theory that every person has a certain speed of movement, a frequency of image that changes in eyes by which the mind is almost completely blank. Brain is free from thoughts and is solely concentrated on processing those moving images that you see. For some people that frequency is achieved during walking, other by traveling by train, and I find my own mental-free velocity white riding the road bike. Solitude and pleasant scenery makes some special feeling inside. I won’t try to explain that feeling, you should find out for yourself.
