Just asking.

Explain kekkai genkai now.

Well, what I meant is that I think you probably use every part of your brain, not every neuron.

Instincts exist too. I’m pretty sure your instincts are the fastest reactions you have, I think your instincts are also faster than the fastest possible reaction time.
Basic instincts: oh no something is coming at me I will dodge

You can’t.

If you only used 10% of your brain, the other 90% would be useless. You could remove 90% of your brain and you would be fine. But you can’t. I doubt that you only use 10% of your brain. I think you probably use 100%.

Apparently there are spots in your vision you don’t actually see, your brain just guesses well.

So… when you dodge something, you’re actually 80 milliseconds slower than the time it takes you to react?
