We do not have Canadian data and we rely on the U.S. data. The integrity of the data that we might be able to pull out in Canada suffers from the fortunately small size of the community. But in the United States they originally saw anomalies after the first Gulf War and they saw a higher incidence of ALS in Gulf War veterans to the extent of something between 50% and 60% above the norm. They then did some further research outside the Gulf War and looked at military people in general, and looked at both combat and non-combat, going back as far as the Second World War. And again, the likelihood of ALS in the military community in the United States is somewhere around 50% higher than it is for you and me.
There are a lot of opinions and speculation about why that may be. The common one, of course, is that those involved in military service are exposed to environmental things that you and I are not. Maybe it's a predisposition and it's triggered by the environmental conditions. But the good news is that Veterans Affairs in the United States saw the relationship, and notwithstanding that there wasn't a cause-and-effect component, they went with this presumption and made that decision. And that has now been moved over, thankfully, to Veterans Affairs Canada.
