On The One Hand...

Ailz dropped a pair of tights on the stairs. "Don't forget the pair of tights on the stairs," she said. "I won't," I said. A minute later I was going downstairs and trod on something soft and slippy and my feet went from under me and the papers I was carrying went up in the air as I grabbed for the bannister and somehow or other kept myself upright (though slanted) and avoided breaking my back. 

Reactions: still pretty fast

Short term memory: lousy.
