@pastanaga - Just be careful with assumptions like that, because allergies can quickly become a very serious problem. You might think it's easy to live with the occasional rash or watery eye, but that can eventually lead to breathing problems if your exposure is enough and you've got a real allergy.
I have a dust allergy and it usually just makes my nose run if I'm in a dusty room. But one time I was having to clean up a room that hadn't been vacuumed for a long time and I managed to get some dust in my eyes and face. Everything swelled up much more than I expected, including my nose and even my eyeballs. It was actually quite frightening and made me realize I should take my allergy more seriously. If it could affect my lungs in the same way I would be in real trouble.
