Interesting Fact - Castles

I ran across an interesting fact this morning regarding castles. Here is what I found:

Spiral staircases in medieval castles are running clockwise.  This is because all knights used to be right-handed.  When the intruding army would climb the stairs they would not be able to use their right hand which was holding the sword because of the difficulties of climbing the stairs.  Left-handed knights would have had no troubles, except left-handed people could never become knights because it was assumed that they were descendants of the devil.

It amazes me that such thought was given even to the stairs. I mean really, who thinks of that kind of stuff. I suppose that's why I'm not an engineer. If such thought was given to the stairs, I can only imagine what they came up with for the heavy duty defenses. Human ingenuity is amazing to me. Given enough time and resources, we could be really scary.

As it stands, we are well on our way to some very Star Trek type breakthroughs. Check out this article:

So what futuristic invention would you like to see in your lifetime?

The geek in me wants a light saber. The adult would like to see medical breakthroughs that save lives.

Don't be shy, tell us what your dream tech would be.
