Allergies. Many people have them and some allergies are weirder than others. So do you have any? Or had any? I used to have a cat allergy but that went away as I got older.
My current allergies are:
Ants: With ants I get itchy and my bite gets inflamed
Trees: I get really if I touch a tree trunk
Grass: If I lay in grass my exposed skin gets ready, itchy, and slightly puffy. Resembles a sunburn x.x
So what are yours that you know of?
