Mark Zuckerberg hopes that Faebook's users will share their organ donor status on the popular social networking web site, as they do with their everyday habits.

On "Good Morning America" on Tuesday, Zuckerberg and company Chief Operating Officer Sheryl Sandberg announced that Facebook is letting U.S.and U.K.-based users add whether they?re an organ donor to their timelines and the story behind the decision to become one. There's also a link to the official donor registry for those who want to become a donor.

This will be part of a larger Health and Wellness section in the biographical information, including details such as a member's weight loss.
