  Now, some people will claim that having 8-character indentations
  makes the code move too far to the right, and makes it hard to read
  on a 80-character terminal screen. The answer to that is that if you
  need more than 3 levels of indentation, you’re screwed anyway, and
  should fix your program.

  Functions should be short and sweet, and do just one thing. They
  should fit on one or two screenfuls of text (the ISO/ANSI screen
  size is 80x24, as we all know), and do one thing and do that well.

Maybe you need to use more helper functions?
