I have an example for you: high-income country germany:

1. Germany has frequent blood-shortages, that lead to less planned operations or even no blood for urgent operations- every donor can at least safe life quality or even lifes in that periods of time
2. In Germany one donation can be stored up to 42 days (or much less) - there is limited recruitment time, if storage is low.
3. Over 12 % of the germans, that can donate blood, do so - there are just roughly 7 replacement people per donor
4. many blooddonations are devided in their different parts - blooddonations are also plasmadonations with added material for other usecases
