Everyone asks that lol. No, they've been like that since I can remember. Apparently it's down to something with my thyroid gland. Can't explain further as I genuinely have NO idea, but I was diagnosed with something a few years back and apparently eyebrows like I have is one of the symptoms. Doctors don't know why, just happens.
Seems more like a positive then a negative to me, don't need to worry about those big bushy brows haha
