Deep Rooted Thoughts

Why isn't everyone interested in discovering their heritage? And why is it that the ones that ARE interested are usually the "over 40" crowd? Nearly 25 years ago I spent my first year of college in England. I visited Scotland and Wales and never knew until this past year that I had cousins in all of these places. But if I HAD, would I have cared? Why didn't my mother and grandfather have an interest in learning about all of their cousins? If they had, I might have spent my summers in Newfoundland!
