How to edit videos/sound on my iPhone 4S?

Will I lose all my app data if I update to ios 7?

I know that ios 7 won't be coming until this fall, but thinking of updating raises many concerns. I already know that all my pictures, videos, and apps won't get lost if I back it up on my computer, so don't bring that up. What I'm really concerned about is if all my app data would get lost if I update my iphone to ios 7 even if I backed it up. I have a lot of games that I've spend a lot of time to get to higher levels, namely Injustice: Gods Among Us, Bike Race Pro, and Bookworm Heroes. So I really don't want to do them over again.

Will updating to ios 7 save all of my games' data? What should I do if it doesn't?

Why are humans so incredibly stupid?

I'm not calling myself superior, but think about it! Some litter for the heck of it, Some claim they care but really don't (PETA) and some are just fat dumb Homer Simpson clones!
So why are there people that just screw nature, think themselves superior to everything or claim they are psychic? Why would mankind be superior to animals? Intelligence? Most humans aren't even smart enough to go one day without their iPhones and go out into the wild! Animals are smart enough to have survived for billions of years! Humans can't even leave their own city or they'll lose Internet connection!
