I've done the falling with no idea how it happened - fortunately, both times I was in my yard so just went flat on my face on grass. I never realized how much softer grass is than floors inside the home. I have tripped several times over the difference between hardwood and carpeted floors. However, this only happens for me when I am extremely tired and I can't seem to lift my feet enough to step up the 1/4"! As has been pointed out here, you will learn to make adjustments so that you can continue with your life. Good Luck!
