Yes, it's a very interesting observation and I think an area of concern.
No, we have not been asked. What we're doing right now is providing the platform, which for the first five years is strictly going to be for research. Anybody who has a research project and who is interested in studying any issue that may have an impact on brain functioning is free to do so, and we facilitate that. However, we had not had a request for that particular type of a scan on people who have been on anti-malarials.
