It's National Blood Week and efforts are being made to raise awareness of the crucial role blood donors play in saving lives.
A quarter of us will need a blood transfusion at least once in our lives.
Yet just 4% of adults in the UK are registered, regular donors.
Marcy Dixon from Carlisle had to have a blood transfusion at just seven weeks old in order to undergo a heart operation.
The process had to be repeated last year when she was four years old. She knows without donors she would have died.
Kim Inglis reports.
Blood donor sessions take place all over the country throughout the year. NHS Blood and Transplant holds more than 26,000 blood donation sessions a year across England and North Wales.
