High level poker requires a substantial degree of autonomic control. Autonomic control is at the heart (pun) of most successful repetitive athletic endevour. continued excellence (strived for, or achieved) at high-level tournament poker should be regarded as at least a 'fringe' sport. intense concentration is taxing if repeated... (re: your/my last birdie-double... athelete?)
poker can cause great physical stress... is that a sport.. just to endure? i dunno.. it Is just sittin in a chair...
