In 2006 Carol Bren's daughter was sick after having her first menstrual cycle. "My daughter was 12. She had her first cycle and she lost a lot of blood so she had to be in theICU and had a blood transfusion and platelets," said Bren.

Now as a way to give back, she donates blood.

"It's a good cause for the people that needed blood and can't donate it. And I enjoy doing it. I'm O negative, and that's what they really need," she added.

Shawn Geddes, a mobile unit technician for the Red Cross said people have pre-conceived notions about giving blood.

"That 'oh I need to keep all the blood that I have.' I personally like to consider donating blood as a human oil change, so to speak. It's nice to be able to give blood so that you can encourage your circulatory system to keep that process going," said Geddes.

There are lots of interesting facts about giving blood.For example, donors can donate specific blood components like red cells, plasma or platelets. Platelets must be used within five days of donation. That's all according to the Red Cross.
