I tend to be cautious. My professional experience in nursing has made me all too aware of potential injuries and my personal experience in motherhood has just confirmed that. (Think about it--in five short years, we've had two broken arms, a broken leg, countless elbow dislocations and a seizure).
Frankly, I am a ninny. I have successfully avoided downhill skiing, scuba diving and high ropes courses so far. I don't even bicycle too fast if I can help it.
But, this sort of caution limits your vacation experience, so it was good I had the peer pressure of the adventurous Gemmers and Joe to gently push me into trying new activities.
