Well, since I've been using Brain Age for a bit. I'd thought I'd say.

It's very useful when looking at trends. About a week ago I nicked my head on the side of the car, causing a bruise or something painful to appear there. Anyways, a week later and it seems like the bruise disappeared. Although now my scalp is kinda tingly. (Usual I guess.) I think that my vision is getting worse, but I took my Brain Age today and... It's at 21. A new low. Strange.

I took the memory test (They have you memorize 25 numbers) and I ended up remembering 22 of them. A new high.

I dunno, I'd figure at around this time if it was a concussion my brain would be further down the stupidity rabbit-hole. So I guess I'm safe?
