Is there a world record of empty lugs? like breath out all the air in them?

Question

i can do this for 1min ;) haven't really cared to try longer

Answer 1

the one above is right you always have about 1-2 lts of air in your lungs

Answer 2

its impossible to completely empty out your lungs, because even though you have breathed out as much as possible, you still have air in your lungs. they wont deflate, silly. unless u get a collapsed lung and/or die maybe? lol!
