Giving blood is safe, simple and it saves lives.
If you are in good health, weigh at least 110 pounds, have a photo I.D. and are at least 17 years old, you could be a blood donor. If you're 16 years old, you can donate with a signed parent permission slip.
Of course, you'll have to go through some screening questions and a mini-physical to make sure you can safely donate blood to help a critically ill patient.
Come on, give it a try. It'll make you feel great.
