When I first started using a feed reader, I was very worried about the prospect of forgetting information I'd learned from various articles that I found important. I'm not super old yet, so I was interested in everything from raising kids to getting a job to preparing for retirement. Initially I tried to use Del.icio.us to manage this information, but found its lack of built-in heirarchy to be a big negative.

So I started using JotSpot (now Google Sites) to keep track of everything. From experiences (how to interact with the opposite gender) to academics (programming!) to big life goals, all of the most important "revelations" and things I learn go on there. This personal wiki is absolutely invaluable to me in helping with my peace-of-mind and future planning. Someday, I hope that it will work as a sort of legacy... maybe a distilled version of what I've recorded could be passed on to my kids as a kind of "historical record".

And Google Tasks is awesome. Another commenter mentioned OrgMode, but I find the online nature of Tasks to be absolutely essential. When I sit down to do work, the first thing I do is open a separate tab with Tasks in fullscreen [simple] mode (mail.google.com/tasks/ig), make sure everything's prioritized properly, and begin.

Here's a link to the actual (very readable) report: http://www.iihs.org/news/rss/pr092810.html

And the original article, I think: http://www.csmonitor.com/USA/Society/2010/0928/Bans-on-texting-while-driving-don-t-reduce-crashes-study-says

I think you are thinking of chromosomes, which owe their structure to proteins.
