Gathering data from living relatives

I know we've all wished a thousand times that we'd thought to ask our grandparents and/or great-grandparents about their personal histories. I'm now realizing how little I know about my own parents' lives. In digging through both of their military records, I'm discovering that what I thought I knew is not true. And it's very frustrating.
In last week's Hickory County [MO] Index newspaper, I came across a small article that was undoubtedly submitted by the Missouri State Agricultural Extension Service. They suggest talking with your family during holiday gatherings about their lives. This, of course, is what I suggested in my last blog post.
But wait; there's more!
The Greene County Extension Center has published a 20-page printable PDF called "A History of Me" that's available at http://extension.missouri.edu/greene for anyone to download and use. I'm thinking about printing it out and sending it with our Christmas letter to all my relatives. I have no idea whether any of them will sit down and write down some answers or not, but at least it might get them talking/thinking about information to leave for future generations.
Come to think of it, maybe I should sit down and complete one of these booklets about my life for my kids.
