 Yeah, I think awareness of the options and understanding of those options is absolutely critical. And there's another element, which is your ability to access and use those options once you know that they are there. And that's influenced by things like your financial status, whether you have insurance, gaps in insurance, whether your insurance covers a test or a procedure you'd like to have, whether you have access to specialist providers who cost more. In the United States context, all of these financial issues are really important.
