I was reading something lately that talked about the relaxing and therapeutic effects that the colours green and blue can have on the human brain. It talked about the colour choices people make when decorating their homes and offices with research showing that pastel shades of various greens and blues had calming and relaxing effects, simulating nature. When taken outside, this also proved to be the case, they said, with visits to the countryside and seaside where grass, sky and sea tend to be of these colours. Hence, a certain feeling of wellness and being at peace with the world during and after such a visit.
I then concluded, this must be the same effect (coupled with the awareness and skill required to be in tune with your machine and ride succesfully on two-wheels) when I venture out on, invariably, local country lanes and the overwhelming desire to do the same again soon.
Just a thought!
