If you want to increase your lung capacity to live longer, I suppose you could ask your doctor, but more likely you just need to read the book, 'Breath' by James Nestor. Pages 58-71, but actually the whole book needs to be absorbed and followed.
Forced expiratory volume (FEV). This is the amount of air expired during the first, second, and third seconds of the FVC test.

Abstract
Results
from several studies have described a relationship between pulmonary
function and both all-cause and cause-specific mortality. The purpose of
this study was to investigate the predictive value of pulmonary
function by gender after 29 years of follow-up.
Prospective study with 29-year follow-up of the Buffalo Health Study
cohort.
Randomly selected sample of 554 men and 641 women, aged 20 to 89 years,
from all listed households of the city of Buffalo, NY.
Baseline measurements were performed in 1960 to 1961. Pulmonary function
was assessed based on FEV(1) expressed as the normal percent predicted
(FEV(1)%pred). FEV(1)%pred adjusted by age, body mass index, systolic
BP, education, and smoking status was inversely related to all-cause
mortality in both men and women (p<0.01). A sequential survival
analysis in participants who had a survival time of at least 5, 10, 15,
20, and 25 years after enrollment in the study was also performed.
Except for men who survived for > 25 years, we observed a
statistically significant negative association between FEV(1)%pred and
all-cause mortality. FEV(1)%pred was also inversely related to ischemic
heart disease (IHD) mortality. When participants were divided into
quintiles of FEV(1)%pred, participants in the lowest quintile of
FEV(1)%pred experienced significantly higher all-cause mortality
compared with participants in the highest quintile of FEV(1)%pred. For
the entire follow-up period, the adjusted hazard ratios for all-cause
mortality were 2.24 (95% confidence interval [CI], 1.60 to 3.13) for men
and 1. 81 (95% CI, 1.24 to 2.63) for women, respectively. Hazard ratios
for death from IHD in the lowest quintile of FEV(1)%pred were 2.11 (95%
CI, 1.20 to 3.71) and 1.96 (95% CI, 0.99 to 3.88) for men and women,
respectively.
These results suggest that pulmonary function is a long-term predictor
for overall survival rates in both genders and could be used as a tool
in general health assessment.
