Most people love the high they experience from positively impacting lives of others. As such, they keep going back for more. One website has taken advantage of this concept to help those in need of blood cells.

The site, Thank Your Donor, allows recipients of blood, platelet, plasma, and stem cell donations to share their success stories. They can share pictures, videos, and little blurbs about themselves, which makes the process much more personal.

A little encouragement and appreciation for such services go a long way fostering repeat donors.

If you've ever considered going to a blood bank to donate cells, here is a simple tool to help you find one nearby.
