It is two. Okay.
I guess my point is that you are being asked to look at very complex cases. Some of these cases go back eight or ten or more years. For example, you may have dementia and PTSD. You may have someone who has multiple sclerosis: is there a link between PTSD and the start of MS or an exacerbation of MS, or between cancer and environmental health risks? Or you may be looking at someone who's developed PTSD twenty years after the fact. As Mr. Stoffer rightly says, you're provided with tremendous amounts of medical information from doctors, in many cases your own military doctors.
I'm just wondering how you can make that decision when the doctors are saying that their conditions are linked.
