Come on... anyone experiencing vasovagal syncope at the site of blood or a syringe is going to pass out soon after that trigger occurs. You're going to overreact to a trigger when it happens, not long after the event is gone. That's why people faint at the site of blood when they see it, not dozens of minutes later. "Oh that blood I saw from 30 minutes ago really got to me now 30 minutes later and I passed out"... lmao.
