Well, I used to say it was in my blood since conception since my Mom worked in the industry fo over 40 years. But I actually worked in a printing plant through college, and continued to moonlight there in the busy season for years - until I had kids. Sometimes I came home coated with inky dust when the trimmers and air handling systems malfunctioned. Interesting enough, most of my Mom's coworkers who smoked got emphysema, the rest chronic bronchitis, and unfortunate few like Mom and her close friend got Bronchiectasis.
