Probably because you got covid or sars.. lmtyals my family has been sick with it since you got of the boat there yeller. I eat and breathe it for breakfast. I pulled a string of mucus of my nose and throat that was so attached it bled a lilbit f*** the salt water until after you cough up the string of mucus so thick it’s sealing a lung. Wash hands cough up mucus when coughed lose then pull like a rope. After you pull that thing out rinse nasal passages and gargle all with salt water.
