People say that now there are more allergies than in the past. They say that this is because of pollution, bad habits, a lot of cleaning... but I think that people didn't know if they were allergic or not, there weren't tests to know it.
I know a lot of people with allergic problems, especially to dust. For example my brother is allergic to dust and pollen. I think I´m not allergic to anything.
I hope that scientists can find a cure for this illness, because many people can't have a normal life, they can do or eat what they want.
