I have been contemplating asking this for a long time now. When i do my albuterol inhaler i have to inhale and then hold my breath for as long as i can. Sometimes i can hold it longer than others and have been able to almost guage how well my lungs are doing by how long i can hold my breath. I think the most i can hold it for is a little bit over 20 seconds ( no more than 25 seconds ever). How long can everyone here hold their breath?
