I also have an outstanding sense of smell. When I was in the Navy aboard ship I smelled out three electrical fires while they were still in the "insulation getting hot" phase. Did the same thing numerous times with my aquarium set ups.
If I smell something burning I ALWAYS stop what I'm doing and seek out the source. Got annoying as hell when the neighbors in the apartment complex just upwind of me, who seem to be in construction/demolition started using former structural wood for barbeques. Smell like a, well, house fire.
