That's a good question. We don't know, because we only speak to these people once and we don't follow up with them. They may find a doctor and they may have no problems afterwards, but at the point when we do have interviews, they mention that they have those problems. So it's actually a very good question. If we had a longitudinal analysis, we would be able to get this information and follow up.
