If you want to help save a life, the time is now.
According to Vitalant, previously known as United Blood Services, the July 4th weekend is one of the slowest times for blood donations. But with so many people on the roads, we tend to see more traffic accidents, and the need for that blood is higher.
Someone who's benefited greatly from blood donations is David Rees.
"The oncologist there said, 'yeah you have leukemia,'" Rees said. "'If we don't start treatment now you'll have three to four weeks to live.'"
Rees was 26 years old and planning his wedding when he got that heartbreaking diagnosis.
"I had to be very realistic and said, 'I might not have another birthday, I might not have another Christmas,'" he said.
Rees and his fiancé did get married, and Rees is now in remission after four rounds of chemotherapy and over a dozen blood transfusions.
"I'm going to live life now because I can, because of blood donors," he said.
Right now, doctors have the lowest supply of Type O blood, but all donations are needed.
