I get this with pretty much all perfumes, scented candles, tobacco smoke (oh god the tobacco smoke) and extinguished matches and candles.

With some people I wonder how they can exist with so much perfume poured over themselves that I can't breathe while walking behind them. I just don't understand.

An upside of being smell sensitive is that it helps with debugging electronics. Burnt parts smell very obvious, and I can even smell hot stuff like heatsinks.
