There was mould growing in his furnace's humidifier, and that spread throughout the house. That caused itching, and for this he took generic allergy drugs for a year. That created cancer in his body, and he died. I know it sounds so silly, but it's true. Be careful about the advice these doctors' give, too. He went to a doctor, and the doc said the allergy drug was safe. It wasn't. His humidifier that wasn't cleaned out properly, spread black mould that gave him an allergic reaction. Then he took these Kirkland brand allergy drugs for a year, and that totally fucked him over. I just wanted to share that because I want people to be safe here. Be careful about what you put in your body, and watch out for mould. For my dad his mould was growing in his furnance system. It made him itch, and then he took allergy pills, which weren't safe, every day for a year. Fucked him good. Don't be like my dad.
