I am married to an insurance underwriter. I have learned so much from my husband about risk as it is defined in the insurance industry that I could probably teach a course in it!
Sometimes people fail to go through with plans for liposuction because they have difficulty understanding the concept of risk. The risks of liposuction do exist, but when compared to the benefits, the risks fade away.
You do have to expect some discomfort with liposuction - any types of liposuction. Nothing is completely pain free, nor is it completely risk free. Make your choices based on research - the best decision is an informed decision.
