What's a Little Blood Type Among Friends?

It's a common dilemna for facebookers to decide which friends requests to accept, which to deny, which to place in that group that has little to no access to any real information about you. Personally, I think the facebook gods need to add a new field ...

Blood Type

Think about it. As terrible as it sounds, you get into an accident. You need a blood donor. You arrive at the hospital (which is of course equipped with Cisco wireless). From your hospital bed, you have access to a secure terminal where you can login to your facebook account. You search amongst your "friends" to see who has the same blood type (a feature to sort by blood type would be useful here as well). You click the "Are you really my friend?" button to ask for a blood donation. Seems simple enough.

Well, at least it would help you figure out who your real friends are.

Update (based on comments from my brother, Sean, and in case someone at facebook reads my blog and decides to write the code for this): Probably best to not give "Ignore" as an option. Only "Yes" or "No" should be the allowed responses.
