Most people think about donating blood. However. Very few actually do it. According to experts, though almost 50% of the US population can be counted as potential blood donors, less than 10% ever give. What’s worse is that even the most consistent ones donate an average of just three to four times during their lifetime. The situation is similar worldwide. Now officials in Sweden are trying to change the situation with the help of modern-day technology. The encouragement to donate again begins shortly after the donor leaves the hospital when he or she receives a "thank you" text. Though that certainly helps them feel appreciated, what is even more pleasing is the text they receive each time their blood is used to help someone in need. Karolina Wiberg, the communications manager at the Stockholm blood service, believes this small gesture not only results in repeat donors, but helps bring in new ones. The program that was started in Stockholm has received such positive feedback that it is now being rolled out across the country. However, Swedish officials are not stopping there. They are also encouraging local hospitals to show the exact levels of the different blood groups they have in stock at any given time on their websites. This allows potential donors to realize that their blood can make a difference in saving someone ' s life. While all these programs are great, busy citizens, even the ones with the best intentions have to be occasionally reminded. In order to jog their memories, officials send them text, Facebook, and e-mail reminders. Though that may sound disturbing, the citizens do not seem to mind, given that the messages are light-hearted and fun - things like "We won't give up until you bleed." Though Sweden is currently the only country using modern technology to urge more donations, don't be surprised if more join in, especially if the Nordic (北欧) country's blood banks start to overflow!
