Off topic answer : some years ago, while playing volley a kind finger scratched my eye. So since there my right eye is way weaker against cold air assoult (like air conditioning jets :P). Too bad 1 of these got me in the eye lol...so spent a week of medicins and stuff but getting fixed everyday now :) Thats too bad. When I was a wee lad, I got scratched in the eye by my sister with a stick. Now it's much worse sight then the other one. I was on these eye drops that make your pupils huge for ages, that was crazy. Anyway, wicked work on the sig. You must get a lot of spare time to work on them, yes?
