“If you have a tiresome and weakening cough at the close of winter, and wish to be cured, we would advise you to begin Osteopathic treatment at once, so the lungs can heal and harden against next winter’s attack.”  Still, A.T. Philosophy of Osteopathy.  p.  73.

Another website for free covid testing kits if you live in underserved/at risk areas (Maine I'm looking at you).  You can order a handful of kits monthly.  
People who test themselves know when to self isolate to prevent getting other people sick and that's a good thing.  Stay home and take one for the team.
