Up to check on Barb. And fix the stove. O² level seems good on both. Mine too. Still trying to clear my lungs. This stuff is persistent, if nothing else. Can't imagine how many it would kill in trench warfare conditions like the Spanish flu went thru. Grateful to not be living in a muddy trench in this weather. Exposure would kill thousands all by itself. Resleep soon after stove comes back to life.
