Gary,

I was acutely aware of the hazardous waste thing -- right after they did the implant, they wheeled me into the hospital room where I was to be quarantined, and a guy showed up with a geiger counter to measure the radiation in the adjoining rooms to be sure I wasn't contaminating them. Then they slapped the yellow and black nuclear hazard sign on my door. (Since I've spent a fair amount of my career doing work for nuclear power plants, I saw a certain irony in that.) :p
