I had a chronic stuffed nose into like the 2nd grade. So when I started taking steroids for my nose, I was able to really smell for the first time, and started noticing cooking smells. Overall, kind of meh, missing out on smell is mostly not a big deal. Smell is useful to detect odorants added to dangerous gasses and to know when the cooking is done if your smoke detector is too far from the kitchen, and it can help detect spoiled food (but visual inspection usually works too), but like I don't feel like my life was worse before I could smell, and there definitely wasn't a big step change improvement.
