Mara Altman enjoys writing about issues that embarrass her, like chin hair. She finds that putting shame on the page defuses the stigma. Her latest book is entitled "Gross Anatomy." It explores some of the biggest issues of the day, including "How sweaty is too sweaty?" Her first book, "Thanks for Coming," had nothing to do with public transporation. Altman is a graduate of the Columbia University Graduate School of Journalism. She began her career as a staff writer for The Village Voice and daily newspapers in India and Thailand. She now lives in San Diego.
