Folding@Home - it's a project out of Stanford university for people to use their home PC to try to help understand how different proteins fold. This research may help find a cure for various kinds of cancer, Alzheimer's, Parkinson's, etc.

I've only been here 9 1/2 years. Funny, I went to see my date I signed on, and noticed I had 5555 posts. Of which I am sure I've said at least 7 things worth while. I know I've changed my posting habits on here.
