I didn't realize how big a deal the natural gas related pollution was. As in the post I found out my rental wasn't doing what it should. Turns out a hail storm had crushed the hat above the water heater exhaust. Turns out the resulting air quality in the apartment was so bad my wife's hand writing changed. We both don't remember much from that year, but have clear memories from the year before and after. Luckily we moved out after 8 months and her handwriting returned and our memories got much better. I strongly recommend monitoring your air quality, ideally with a CO alarm, since it's deadly quickly, and something like the airthings.com which monitors PM2.5, CO2, radon, and VOC.
