For the past five years I have been a mechanic working on heavy equipment, i.e. bulldozers, loaders, etc. Not a day has gone by since I started that I haven't come home and had to change clothes befor I entered the house. More than half of my uniform shirts that I wear at work are permenently stained black, front and back from the grease and grime that I am constantly rolling around in day in and day out while repairing the equipment that I work on
