I spent the majority of the day cleaning out the overflow drain on a sink. The previous owners appear to have spent decades shaving diseased ferrets in the downstairs bathroom. Worst part is, I'm now noseblind to rotted hair, so I won't be able to tell if I'm successful or have made things substantially worse until I'm removed from the area and return.
I also suppose I could die from inhaling whatever microorganisms produce that type of smell, so if I suddenly stop making inane effortposts, remember to always wear a respirator. Or snort fat rails right after you inhale potentially dangerous biologics.
