I have, for better or worse, a super sensitive sense of smell and taste. Many common things that people barely, or claim to barely smell overwhelm me, sometimes in a good way, usually in a bad way.
Good:
1. Oranges. I love them, and the more "potent", the better. I scratch them at the store and smell them, and I can tell if one is bad, good, great, or "floral" (The worst IMHO).
2. Steak or burgers cooking.
3. Donut glaze or almost anything with a lot of sugar in it. The story about the guy getting arrested by the cop thinking donut glaze was meth totally amazed me. I can smell it from 10 feet away, and I can't imagine going through life with a sense of smell so bad I can't tell glaze from meth. Crazy.
4. Fried potatoes, any kind, except for those awful hash browns with the peppers in them.
5. Fireworks and smokeless powder. I love the smell of it.
6. My old dog Gus, who smelled like burnt leaves. I have no clue why.
7. Garlic. No amount is too much.
8. Break Free. I love the smell of it.
Bad, and there are lots of them:
1. Ranch Dressing. The vilest, most disgusting thing on Earth. Runner ups are Tartar Sauce, and Mayo. Mustard is up there too. How someone can say that any of the above "doesn't smell" confuses me. Yikes.
2. Tomatoes and tomatoes in anything. Almost as disgusting as the above stuff is.
3. Most laundry detergent and soap. Obviously, I buy the unscented stuff. I can only take a minute or two in the laundry and soap section of the grocery store before I start clearing my throat and my nose starts running. Most shampoo revolts me too.
4. Coffee. I hate the smell and the taste of it too. I can smell a burning coffeepot two floors up in some buildings. I used to come to work at night, walk in the door, and say to the guy I'm sending home, "Where was/is the burning coffeepot?". Most of the time, they would say, "I don't smell anything!". I would look and always find at least one.
5. Poultry. Don't hate it, but I don't care much for it, and I hate the smell of it baking or broiling. Dislike of it runs in the family. I'm the third generation of it, at least.
6. Air fresheners and Lysol. Like tear gas to me. Those oil air fresheners should be labelled a hazard to your health. Same goes for those pine things you hang from your rear view mirror.
7. Baby poop. Can't take it for long. Maybe if it was my kid, I would be able to tolerate it, but since I don't have kids/grandkids, I can't handle it.
8. Cheese. Hate it, but the smell of like Swiss doesn't bother me, but the stronger ones are horrible. I'm the only person I know of who has never, ever swallowed a bit of pizza. I've spit it out in disgust every time I've tried it. One of my nightmare foods where I've had dreams where I was force fed it.
If I ruled the world, so many things would have the added scents put into them removed.
