Ninety-year-old Maude tells the sad story on how she lost her husband.
"Well, he needed a blood transfusion, but his blood type was not on record so the doctors asked me if I knew what it was as they needed to know in order to save my Norman's life. Tragically I've never known his blood type so I only had time to sit and say goodbye.
I'll never forget how supportive my Norman was. Even as he was fading away, he kept on whispering to me, "Be positive, be positive!"
That was my Norman, always thinking of others."
