I can just see you sprawled out on the floor, but you are lucky that you didn't hurt something!!! BE. MORE. CAREFUL!
Vigilance - this is the concept that you are striving for Janet! I'm NOT suggesting you are old - but since I work with older people, I can tell you the ones age more successfully are those that are vigilant. They watch where they are walking, they pay attention to the environment, they look for extra fat/calories in food, they drive more carefully, etc etc. It is true that as we age, we are not as graceful, spry, and agile - so BE MORE VIGILANT!
That said, I have fallen more than I care to say

So, maybe I should take my own advice!
