So for fire training they had us test how long we could go without air before panicking, let's just say when you do breathe in with no are the mask encloses around your face causing your panic which makes you loss control over your exhale- The feeling is horrible omg I've never been more thankful to breath-

MMMM SUFFOCATION IS FUN

No no

Yeah just my throat hurts from breathing all that dry air from the pack's-

and just recovering from some panic xD
