Sure.
In terms of drug costs, the suite of drugs that I was taking prior to my surgery, which is now reduced by virtue of the surgery, had an aggregate cost of about $20,000 to $25,000 a year. I was fortunate to have a medical plan that covered a good chunk of it, but nevertheless somebody was paying that cost.
In terms of the surgery, the surgery is not high-risk surgery. It's relatively routine surgery. But in terms of the selection of patients, I think there's much more demand than there are surgical places available. Therefore, they tend to pick candidates who are good, solid risks for successful surgery. I wouldn't like to hazard a guess as to what the proportion is, but certainly many more people could benefit from the surgery than have had it.
