No matter how hard you try to stay clean...

In our chemistry department, we had a lot of controls on exposure to chemicals: hoods, materials handling procedures, that kind of stuff. The prof who did tin chemistry, and almost all his grad students, had gray hair: a sign of tin poisoning.

I worked in the microbiology department, in a pathogen lab, doing research on mycobacteria, specifically tuberculosis. Every semester we had to get tested for antibodies to TB (indicating that we'd been exposed) and every semester at least one researcher had.

My best friend works as a clinical technician in a lab doing human tissue sample analysis. Pathology lab, basically. About a week ago they had a patient that was *really* sick with a bunch of nasty things, and they were working through samples, and one of my friend's coworkers started screaming because one of the stool samples *moved*. The patient had serious tapeworms, among other problems.

We're thinking about going back to school and becoming art critics.
