Could just be you: Reference ranges are set for couch-potatoes and if you're a well-muscled man, you'll have creatinine high, often above the normal. And ranges are set arbitrarily to have a few percent of healthies outside on either end. Keep managing your hypertension and don't worry so much about creatinine.
A standard chess board has 64 individual squares, but 204 squares if you count squares of all sizes. A regulation board consists of eight squares in each direction.
A chess board represents an abstract space and a chess piece is a member of a set of finite elements where to each element is assigned a rule on how to change its coordinates in the abstract space. These rules also depend on the positions of other pieces. For example, a rule for a bishop is that it cannot proceed past another piece in its way.
