I live in a small ish city and the air quality is much better than most cities but when I have to travel in to the city for work i end up coughing for the rest of the day. On weekends I avoid the city and by Saturday my cough is mostly gone and by sunday its totally gone only to come back on monday. Cars are the primary reason for me wanting to change to a remote job. Not only is riding my bike in to the city slightly terrifying but the damage being around so much air pollution is just too much to make it worth it.
