I wasn't going to admit this, But it can happen to anyone even with someone with life long experiance as I have on ladders,..... 4 years ago inside a new home, I was triming out a upstair window in a 18 x 22 den with 20ft ceilings it was the largest room in the house so I had set up my miter saw in there and had made a lot of dust on the floor from cutting for the rest of the house trim, this window was the last to be finished the job and the closest to my saw work station, I had to move the saw over a few feet to get the ladder stood, I knew the dust was on the floor and simply kicked it away with my shoes the best I could,
I went ahead up the ladder and worked on 3 sides of the window and had to stretch to get to the far 4th side, and this is when the ladder started sliding down the wall because the ladders feet lost the grip to the floor do to the sawdust, the fall was not problem I knew what to do I rode it down for half the way until the top of the ladder came to the large 8 ft. tall case opening in the wall when the ladder went thru this opening I lost my ballance fell backwards my right foot fell thru the rung and when I slam to the floor all my 220 lbs on top of the ladder and ladder on top of my ankle,It was a situation that one person could not get themselve out of, it was a good thing someone else in the house heard the noise and came to help, its hard to figure out how to get up off a ladder when your legs is stretched out under the thing with a broken ankle ,
well I found out how fast a foot can swell when I remove my boot, and can also turn many colors you never seen before

.............. but as I said ..it is the sudden stop I fear,

everyone was amazed that i didn't break anything else at my age of 46 at the time, I do still walk with a limp to remind me of that day
