The amount of air that can be forcefully exhaled after a normal tidal volume exhalation is called the expiratory reserve.

Explanation:

In normal breathing, the volume of air entering or being expelled from the lungs is approximately half a liter (500 ml), depending on the age and sex of the individual.

The expiratory reserve volume is a parameter that indicates the volume of air that is exhaled when a forced expiration is performed, which is more than double the normal expiratory volume, around 1200 ml.

Together with the inspiratory reserve volume and the tidal volume, the expiratory reserve volume constitutes the vital capacity.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
