I wish i could just donate more at once. I am tall and heavy enough with good enough hemoglobin that i reckon i could easily donate twice as much. Feels weird that its just same flat amount for smallest and biggest people. I understand it propably does not scale 1:1 with size but still.

EDIT: amount that is donated each time is less than 0.5l in Finland, i believe regardless of size but perhaps there are size limits for smaller people?
