Here is my cousin Tara preparing for battle with my WWII Japanese Katana.
I say to you, oh bored and shapely Hollywood, why not make this the new exercise trend? Eh? Picture hundreds of sweat-crazed housewives swinging swords about with angst - possibly frothing at the mouth. Think of the publicity your gym would get as Demi Moore accidentally decapitates Muffy the beautician? Its a win, win, really
Besides, Tara weighs about 13 pounds and she can do it! (To all Iaido students - notice the accurate hand positioning?) So to Hollywood, drop the yogurt and pick up that 14th century Katana - at least until the next trend of "Aerobics in full Plate Armor".
