 When I walked through the Nexus or Global Entry lane, Pitcher was taken on my face and I walked through the security very, very quickly because it was all facial recognition. And we seem to be okay as a population with trusting on national security on facial recognition. So if there is still a concern that an algorithm cannot help doctors in our day-to-day practice, or that we shouldn't be embracing others already, well, again, we're all detrusting it with our day-to-day travel going across the border. So the same kind of technology that is behind facial recognition is being used and studied and evidenced in picking up, as you say, cancers early.
