Selects: How Itching Works

Down to like millimeters. Yeah. And the other thing they found out too is that Not only can they sense it from a few inches away, but it's a very slow acting thing, which as opposed to like heat on the hand, like a candle on your hand. I almost said candle in the wind. That's super fast, but that explains why an itch is kind of slow to come and then slow to resolve by scratching.
