Thank you very much.
You went over the process used to assess the physical and mental needs of a veteran. You spoke about the fact that, through their documents and any files that they have, you can see whether or not there were toxic substances that were on the grounds that they were training on, or anything like that. Has it ever happened where they didn't necessarily know of that at the time, so it wasn't recorded, yet people are coming back with a condition that they think may be connected to something during their service?
