Hi Kris
1. Nah, not really, but I've seen a few parts briefly.
2. N/A, and no, unless you're REALLY desperate. It just involves taking care of your skin, using acne cream, and taking lots of showers. However, if I had a lot of wrinkles and looked really deformed and hideous and had no hope the other way, I'd probably go for it.

4. A while ago in 4th grade when I had horrible eyesight and had to wear strong glasses, that was hell and I would have probably considered it. Now my eyesight has greatly improved and I don't need it anymore... but it's kinda hard to think, since back then I didn't know it even existed.
