In the winter, the fleas are going to die. So it's not going to have the same effect across Europe in the winter, but it's going to reoccur during this 8 year period every spring and then it's going to do its havoc. And in some cities they lost 20 or 30 percent of their population. Other cities lost up to 70 or 80 percent of their population. So there's, my brain's exploding. There's so much to talk about in terms of why was this allowed to happen, what was the current present thought on disease, why did they think this was happening, how did they react to it, and eventually what are the effects. We always have to get to the effect.
