Sounds like you are both in agreement. BeachGirl says that everyone has a different level of acceptable risk. Jiro says he would not accept any level of risk (I assume he would not even accept a Zero level of risk). Both have come to terms with their own level of acceptable risk.
I (since I have a CI) have obviously accepted a higher than zero risk. However, I am on the fence for a second CI. I have to once again gauge the level of risk I am comfortable with before proceeding with a second CI.
