I have knocked over many a cup, tripped over many a time and hammered my thumb more times than I care to remember over the years. Could I have avoided each of these accidents? Yes, probably I think I could have, because I was careless and didn't take enough care over what I was doing or not concentrating at the job in hand. Will I knock over any more cups, trip or hit my hand with a hammer again? Of course I will. Same as I might have an accident on my bike at some point in the future because I take a calculated risk every time I get on a bike with the way I decide to ride it. I don't believe anyone has said all accidents can be avoided, just that our own actions play a part in how much risk we choose to take and therefore how many "accidents" we will have.
