 But if you notice, you know, my bowels don't work right since the whole COVID pandemic. How do we know? How can we go back? Now, if we do find out that COVID persists and hides out in the body and we have a way to test that, that could help. That could actually be very effective. But right now we don't. We don't even have adequate COVID tests because people who have COVID aren't testing positive. We really need to update our tests.
