"structuring water" ??

Hey Trapper. I was doing some reading on here about distilled water and the various debates and what not in the Barefoot forum and I found a post from you where you stated:

"everyone in the know structures their water, even those who dont use distilled. it only makes sense. i let nature structure mine in a glass jug out in the yard. it is wonderful."

^just wondering if you can explain what "structuring" your water is, and what leaving it out in the yard does? I finally worked out my water situation and a distiller is being shipped to me now. If there is anything else I can do besides distilling to make my water healthier, Id like to know. Thanks!

P.S. Going back on iodine finally too! Woo!
