Some people can keep their regs out of their mouth for a longer period than others....so is this a reflection of what?
Lung capacity? Does exercising help this? What can be done to improve the ability to 'zzzzzzzzz' longer without having the urge to breath.
I'm not interested in voluntary hyperventilation in this case....
Thanks,
