This was the winning unanswerable question in an Omni Magazine contest several years ago.  So far, I've never heard an explanation!

The feeling of being tickled is a reaction of not wanting to be touched. This is why the exact same touch is ticklish from one person and not another. Laughing is the response to show that intellectually you don't mind but subconsciously you do.  Since your touching yourself you don't feel threatened.

I totally know what you mean. I used to think about that all the time, but I would just exhaust myself. I think the only sure thing we know is that we know nothing. I am a bit of an agnostic, but certainly don't think that everything just happened by chance. Was there ever nothing? If so how did we ever get something? If scientist say there is an end to the universe, what is it like a wall? Plexi Glass that you just bounce of of? Or is it like Pacman where you just pop out on the other side? There is so much that is just unexplainable in t his world. I am just glad to be a part of it. I have pretty much given up on trying to figure it all out. While I am in no hurry to die, I am somewhat excited at the possibilty of everything being answered once I go. Good luck in your search for answers. We need the Teacher's Edition of the bible, one with all the answers in the margins( I wonder how much that would go for on eBay?)

I read that book. I'd be glad to help you, it's just that we don't know what to answer. You didn't give us the questions. Please put them up.

Say what? Congratulations for asking the most confusing question of the day! I've read it three times and I still haven't got a clue. Congratulations also to the gentleman above who did understand and gave you that exhaustive response. I hope you understood it and it answered your question (whatever the hell that was!)

What is there to explain???

No one knows the answer.  The bible thumpers try to blame it on God but it doesn't answer the basic question of "Why?".  There is not yet a satisfying answer that I know of.

I'm thinking that there probably isn't enough information here to figure it out... this is a pretty vague.  I wish you luck, though!
