What do you mean with "lives saved by donating blood" in the first place?
Quantity people who would die without any blood donations
Liters of blood donated
That's not a pretty useful number if you want to make personal decisions based on it. If our Western system would need more blood, raising the incentives for donations isn't that hard.
WHO prefers all blood donations to be unpaid:
"Regular, unpaid voluntary donors are the mainstay of a safe and sustainable blood supply because they are less likely to lie about their health status. Evidence indicates that they are also more likely to keep themselves healthy."
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
