Yep, just look at it as micro, micro blades in your lungs. Breathe in, slice, slice, breath out, slice, slice. Sometimes in some years, Eddie doesn't have to plug in his Hurrican fan, to keep the dust, and insectavores away......of course, he can't sit outside either, without taking a chance of getting clocked by debris coming off of his neighbors house. Course, his knapping tools, and rock, will be come debris also. His neighbor, will be wondering where these arrow, and spear heads stuck in the side of his house, and trees, came from. And that stick with a piece of copper on the end......
