"And then one day you find
Ten years have got behind you
No one told you when to run
You missed the starting gun"

It's both. It highly depends on what the person themself likes, but what they like is also noticably influenced by their culture and society.

probably C or C++

Right about zero times

(a+b)(a-b)=b(a-b)
-> You cannot divide by (a-b), because a = b, therefore (a - b) = 0.

When I was about 10 I saw Saw and that totally disturbed me for the next few weeks.

That's a very interesting question and I'm not sure if I have the best answer to it, but here's what I think. People like not to suffer, so I think it is kind of comforting to see others in pain because you know it's not you and that you are safe. You basically realise that you are in a better situation than the other person.
