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.
I base this on a simple observation: checkers has 32 playing squares and 24 pieces; chess has 64 playing squares and 32 pieces; Go has 361 playing points and up to an equal number of stones.
