Volunteer Physical

Today I went for my physical to be a volunteer at the hospital.  It was from 12:30 until 4.  The two volunteers were in with four new hires.  I had to take a drug test among other things.  I've never had a drug test as far as I know.  I also don't remember being tested for color blindness.  I have to go back Friday for them to read my tb test and then they do another one after about a week.
