@KoiwiGal - I wonder how much garlic you have to have before it really changes the way you smell to the point where it's not just on your breath. I've never noticed that with garlic bread, but I guess I've never prepared it from scratch either.
I read recently that there are some scientists currently working on developing a deodorant that works by providing your body with new bacteria that overcome the ones that cause bad odor. The theory is that these bacteria are what horses and other animals are collecting to deal with sweat when they roll in the dust and that we should have them naturally as well, but we remove them with soap and they don't grow back as quickly as body odor bacteria do.
I think it will work in theory, but honestly, I really enjoy having a shower each morning, so even if I didn't have to do that I think I'd still want to.
