More power to you: do both! Martial arts for 10 years at 36 helped me kick the last remains of the drinking habit and taught me how to fall head-first down stairs without killing myself and give a junkie attempting to steal my 3/4" thick electrical cable a shock: he never thought a 5'4", 54yr-old woman that he tried threatening would rip it out of his hands and whip him with it. Oh and I took up (athletic, not stripper) pole dancing at 43 too. Physical skillz get the brain back on track
I can only imagine the look on that poor bastard's face :D
