My blood type made me a donor superhero – until my weakness for crisps let me down
The article highlights the author's experience as an O-negative blood donor, which is considered a "superhero" blood type due to its universal compatibility. However, the author was turned away from donating blood three times because their iron levels were slightly low, which is a common and natural variation in humans. The article discusses the strict rules around blood donation, where a three-strike policy can prevent donors from donating for up to two years, even if their iron levels are only marginally low. The author expresses disappointment at being unable to continue donating blood due to this policy, despite their perceived superiority of having the O-negative blood type.
