The Place that I worked at here in Arkansas, was crowded, and greasy, and loaded with rust from abandoned, outdated industrial equipment that it was my job to disassemble and to catalog the parts.
The people that I worked around have poor social skills, and disorders like down syndrome.
Just for the record, people with down syndrome have compromised immune systems because it is not just mental retardation but a physical abnormality.. so they're constantly vulnerable and bringing in bacteria and viruses.
Just to add to the pre existing condition of the facility being nasty in and of itself.
People have even gotten so sick, that they had acute heart problems while performing their duties, and had to go to the hospital immediately.
So its a very tough, tough environment to work in.
