Right, the mental illnesses for sure. I would say probably environmental. The military does a lot of sampling of environment and stuff, but I think we probably don't know the environmental impact Afghanistan is going to have. It's different soil and different air.
I would have to say that I think probably the thing that is the most difficult to discern, rather than diagnose, is the impact on the family. I think that's where we really need to put some resources. We are really starting down that road with our research community as well. But we know there are impacts on the spouse and the kids. There are transgenerational impacts that really need to be investigated and are difficult to diagnose, because the family is not in the same health system as the member.
