Yeah, that's huge! If I get injured, I'm not completely SOL because of my species. I mean, I can lose an absurd amount of blood before it becomes an issue, so I'm not in as much danger as a human. Trolls are tough like that! But there isn't anyone else like me on the station, and even if there were, they'd have to be a teal like me before I could get a transfusion from them.
