Weeeell, I'm pretty strong. Especially for my age, I'd say. Like, if you were a weedy kid in a group, you'd want to enlist me so that I could kick the living shit out of all the other kids. But sometimes I see someone my age and they're built like Schwarzenegger and make skyscrapers look diminutive. And that's just the girls.
I'm good for an impromptu wrestle and have a decent pain threshold. I only yield when I know that something is about to rupture. I bloody love fighting, but my opponents often take it that bit too far and I don't give up in time, so I usually come out of it with an injury or two. Or fifty. Very injury prone. My fault, mostly. Good bones but shit joints. Otherwise, yeah, I could take on most people my age. For lack of defeatism if nothing else, really.
Emotionally, on the other hand... my anxiety pushes me face down in the mud but my inherited fortitude always has me rebounding. Still, I don't know of trauma in any great sense, so only time can reveal the extent of my mettle.
