if i forget a face or get caught in extreme anxiety my memory is horrible, otherwise it's really really good. I mix up words sometimes though and I think the owner thinks I'm retarded because of the brain injury. No, I think too much because of the brain injury and I'm prone to seizures and panic attacks but I'm so good at controlling them most of the time, even without the prescription pills, it's hard to tell. I know where I might have issues but might isnt a definite and as long as I stay hydrated I can handle under 100F
