Improve your chances, tip # 1

My maternal grandfather always carried a hanky. The accessory fell out of fashion in my parents' generation, but I tolerated teasing from kids in school to be like Papaw. Over the years, the standard piece of white linen in my pocket has evolved into bandanas running the color gamut. I don't leave home without one. The uses are myriad; hygiene, food processor (crushing, soaking, straining), water filter, first aid (tourniquet, bandage, sling), hat, sleep mask, storage (hobo bundle), germ/pollution protection, glove/wrist guard, sweat band, identity concealment, fire assist (char cloth, cotton fire roll), binding/cordage... why aren't you carrying one too?
