When I was younger I went through a actually terrifying stage in my life. I had regularly been extremely fit and healthy growing up, and I never had any problems with my body condition or overall help. And then, I hit 23 and my body completely fell apart. Suddenly, I was mysteriously plagued with all sorts of weird health issues and ailments. It felt like one sickness after another and I could not decide if they were connected or not. I spent a lot of time in bed that year at the mercy of my central cooling method and forced air furnace for any sort of comfort. I could barely leave the cabin because I was so exhausted, so I never got natural air. I exclusively breathed indoor air and racked up enormous energy bills from abusing my Heating & Air Conditioning system. The only time I ventured out of the cabin was to drive myself to multiple doctor appointments. Unfortunately, I eventually found out that this was section of the problem, however every time I got back from one of my doctor appointments I felt much worse and my breathing was severely limited. I thought that I was allergic to something outside so I spent even more time indoors, basking in my central heating and cooling. It wasn’t until a year later when one of my friends borrowed my car for the day that I realized the truth, but my old car had been leaking refrigerant for a actually long time. It was a slow drip that didn’t stop the A/C from toiling… but it absolutely wasn’t nice for my lungs. Every time I went to the doctor, I was entirely making myself sick with low quality indoor air.
