A very basic estimate to answer this question is to calculate how much air you breath in and out with each breath, and then compare that to the amount of air we could breathe in the atmosphere.
The diameter of the earth is about 13000 km. Let's assume that atmospheric pressure is 1 ATM from sea level to 1 km in altitude. Calculate the volume in this slice of atmosphere (ID = 13000 km, OD = 13001 km). Humans breathe in about 500 mL of air per breath. Compare these two numbers for your basic estimate.
Of course this is not really right. CO2 that Shakespeare breathed out is probably part of a tree or stuck at the bottom of the ocean, but that's no fun to calculate.

If a person has alcohol on his breath, they were probably drinking therefore they would most likely have an altered state of consciousness.
The deep muscles of the thorax that promote inhaling are known as the diaphragm muscles. These are the muscles that are activated when a person has good posture and takes a deep breath.

People with lung disease may be more likely to have shortness of breath.
Yes, aerosol sprays can cause shortness of breath when inhaled directly or in confined spaces with poor ventilation. This can be due to the chemicals or irritants in the aerosol affecting the lungs, leading to respiratory symptoms like coughing, wheezing, or shortness of breath. It is important to use aerosol sprays in well-ventilated areas and avoid inhaling the spray.
