Well I lost a lot of blood after having an emergency C section after being in labour for 36 hours 26 years ago. I had already signed the forms to say I did not want blood beforehand.
At that time, even though obviously I didn't want to die having my first baby, I truly believed that if I died I would wake up in paradise but that if I took the blood I may live temporarily but would not get through Armageddon and would ultimately lose out on the 'real life' in the new system.
Fortunately I didn't die then and got to bring up my baby. But guess I'm going to die now (one day).
