Think Before You Bleed

As I donated blood today, an incident happened on one of the other couches. The donor became light-headed and nauseous shortly after starting to donate. The following conversation ensued…

NURSE: Did you eat breakfast this morning?
DONOR: No.
NURSE: What did you have for supper last night?
DONOR: (head shake with mumbled negative)
NURSE: What were you thinking donating blood when you didn’t eat dinner last night or breakfast this morning?
