...I was greatly influenced by the philosophy of a planner involved in designing a university campus in the USA. When all the buildings had been built all other ground areas were grassed over and no solid walkways put in place.
One year later they looked at all the worn out grass that had been made by the students making their way between buildings using the shortest routes, and only then made solid walkways.
and this is the method you used when deciding on your hairstyle?
Oh, and I don't think a NFR section is a good idea, as explained by so many above.
