 Biochemical could be anything. It could be the food you're eating. But let's pray for you right now because that's so debilitating. So many people who are struggling. Cancer in some respects. My own father-in-law came down with cancer. I remember one day he was out helping my brother-in-law and he got so fatigued and he didn't know what it was. He eventually went to the doctors and they found he was diagnosed with that. So don't put it off, okay? We'll pray right now for your complete health and total recovery. We'll pray for those two friends who are paralyzed.
