Oh there's a few; I'm a big fan of general 'clean' smells; walking into a recently cleaned like building or apartment, and the scent of chemical cleaners makes me feel so nice. Also why I tend to like hotels and hospitals. I also love minty scents, I got this spray from wholefoods that smells just like green scented markets. I also like some smells like gas and construction and rubber, they remind me of some places I've lived :3
