They could only make it easier for you by barging into your house, jamming a Q-Tip inside your mouth, and then running out again.

I don't really care much about my body parts. I mean, I do...but I mean "don't care" more in the way that I would happily give a kidney or some bone marrow or half of my liver to someone else who needed it. I mean...kids with cancer, yeah? Bone marrow transplants can save their lives. I know why some people might balk at the thought of giving their kidney to someone - especially someone they don't know - and I get it. But I just kind of feel like...we have these bodies for such a short amount of time, and if we're really honest with ourselves, we really don't appreciate them as much as we could. So why not give something of our bodies to someone who might?
Then I read this article about an organization called Be The Match. Not only is the story of how the org was founded illuminating and motivating, but they make it so easy to join the registry.
And in all seriousness, it is the easiest thing in the world to get on the donor's list - they send you the kit through the mail, which takes five minutes to complete (maybe 10, if you're super careful like me), then you drop it in the mail again (postage paid!) and you're done. If you match someone who's on the list as needing a donor, they'll tell you and you can go from there. If you don't, you still get to have the heart-warming feeling of doing something good and giving for your greater community.
So do it. Yeah, do it. C'mon. Do it. You know you wanna do it. Just do it.
