Meet Jenna. She's 19 and she's inviting the whole country to her 21st birthday party. To attend, all you have to do is register as an organ donor. Why? Jenna needs lungs and the more people sign up, the better Jenna’s chances of being at her own 21st are. Sure, this is a very, very clever ad campaign, but don't look at it for that. Look at it as a chance to really help people. Jenna is really sick, as are thousands and thousands of other people. An increase in organ donors could help everyone on the waiting list.. Visit the campaign at www.getmeto21.com or follow the hashtags #getmeto21 and share the hell out of it. One donor can save seven lives. Spread the message and see how many you can help save.
