What would you take with you? Is less more?

I have been reading blogs for a long time. A couple years ago I had family tell me to start a blog. I just never thought I could be that open. Just a few days ago I decided to look further into it...posted, posted a picture and stated... "This is my first blog, but I don't know if I will come out of the closet yet". I then posted on a blog I frequently read and my photo came up! WOW! I felt exposed! Quickly I deleted my first post and have thought about it for a couple days. I will post and see how it goes...or doesn't go.

I imagine my blog about fun times, people in general, decorating, food...and more food...and least of all about me, until I get brave. My first question would be to anyone who happens by this way. If you could go back in time to the Civil War era, with one piece of knowledge you currently have. What would you take with you and why? Would your knowledge change humanity?

I have often wondered about this. Spurred on by the Amish influence in my life. The main thing I noticed about an Amish life style for me is that I would have to get used to new smells! (no daily showers) And less mobility. Sometimes the simplicity may be nice though. If I could go back with one piece of knowledge it would have to be something about bacteria or even infection and how to fight it.

for fun check out http://www.youtube.com/watch?v=GsfVw9xxoNY for Weird Al's version of Amish Paradise. He is pretty close to right on from what I saw.
