Just wandering about.

Just wondering why the alpha channel is the fourth channel
Just wondering why bats fly but wombats don't
Just wondering why there have been more wars fought for religious reasons than all other wars combined
Just wondering why the banning of plastic bags makes paper bags that used to be free worth a dime each now. Paper bags where free before plastic bags where invented and recycling of paper was wide spread.
Just wondering why the sport of modding computer games is not in the Olympics when the other sports I enjoy, cycling, running, skiing, sailing are.

These questions have no answers or so many different answers as to make thinking about them a pointless venture.

Now here is a really silly question.
Why am I awake in the middle of the night thinking about these things?
