I don't have allergies but my sisters do, so I've been thinking and I was wondering what causes allergies?

But you know what's weird? My DOG is allergic to something too!! I think that it's very random!!

Allergies are a direct result of genetics, or environmental issues in humans as well as canines.

Your metabolism may be different from your family; and that is when a glitch happens in your DNA, probably resulting from maybe 100 or 200 years ago.

Please don't use coloured type, it is too difficult to read.

That sounds very interesting :)

... anyways I'll try not to use color but its so enthusiastic!! :P

that sounds very interesting :)

...anyways I'll try not to use color but its so enthusiastic!!! :P
Colors are also very hard to read and make you look like a little kid without much important to say..

Well I am only 12
