I was going to say that PET is superior to SPECT for many things, like the diagnosis of cancer, so you're actually looking for a better test. So if we go the PET way, we actually are going towards a better test.
Going back to TRIUMF and the photofission, that's research. That's something that may or may not work out. It's sort of a speculative, almost penny-stock kind of thing, so we don't know if that will work.
We do know that PET works. PET oncology scans work right now. If you go to Quebec and you have cancer, you get a PET scan, and you are glad you have that opportunity. In Ontario, it's very limited, so right now that's an issue. We'd love to have a PET scan for cancer in Ontario.
