It's hard to explain. I'm really good at catching things that unexpectedly fall. A little like Spider Man, except better.
For example, in my shower at home, there's a bar about 6 and a quarter feet high that I keep shampoo, body wash, etc on. Because it's in the shower and it's a really slick surface, the stuff regularly falls. I catch it every time though. Once I caught it while I wasn't even looking at the bar. Facing forward, put my arm behind me, and caught an object I couldn't have known was falling.
