Falling over

Am I old or what - I keep crashing and burning....

1. I crashed a few weeks ago on my mt bike and got all bruised up
2. I took two tumbles while backbacking two weekends ago

And then last nite, I was washing my hands at my bathroom sink, stepped backwards to get a towel and completely fell over backwards.....over my speed bump of a yellow lab who was laying down RIGHT behind me! There was no hope. I did not see her and the next thing I know, I am on my back on the floor! I hit my head on the marble floor. Stupid dog!

At this rate, I am going to break a hip before I am 45!
