I think it's a little early to tell what the economic impact will be. This year our cattle prices have been particularly high. The demand for beef has remained strong in this country, even though there was the single find in Canada earlier this year.

Now, the impact on export markets - we export about 10 percent of what we produce, so obviously that will probably have some impact on the market. At this point it's too early to determine how much.

It's been studied to the point where we know that the impact on humans would be from consuming the most infected parts of the cow; that is, the brain and the spinal cord.

I'm confident that we have measures in place. And the additional measures that we announced yesterday will be even more protective of our food supply in this country.

Blanket objection is not very reasonable to me - any effort to control scientific advances is doomed to fail.

It feels great to discover a planet, just like any discovery in science, except that it has more of the feel of exploration - you can go back and look at it. However, I can never visit.

Me and Sheamus have a natural chemistry.

I think we perhaps are, with sleep, where we were with smoking about 50 years ago, in that we had all of the science, and it was right there for the public discussion, but it's not yet adequately sort of percolated out into policy or even just public wisdom.
