Thanks for the detailed response. I don't deny that it might be difficult for someone to work without ventilation. I simply find the air outside extremely irritating to my throat, nose, and upper airways. This "fresh air" frequently gives me headaches, which rarely happen if it is kept outside. I wasn't prone to headaches at all before I started working here. I rarely open windows at home and feel fine. It seems to be a no-win situation, and the better solution for us is to part our ways, which I am working on.
