My Chickasaw mother was a pioneer in the field of Occupational Nursing. She ran the medical departments for Reynolds Metals, Oregon Logging Supply (world's largest) and the Port of Portland. She was a founder of an organization that grew to 10 western states with 3500 members who worked with legislators and industry to bring to fruition the safety laws protecting blue collar workers today. I excuse your gross ignorance on the subject and inability to do your homework before forming an opinion.
