Test your lung strength [🎞️ thebrainmaze]

I passed out and woke up on the floor before it got to the B. Is that good?

Smoked for 20 years and held while it played twice on half a breath, shit test 😂

held for 3 complete cycles of the video, and I have had respiratory issues off and on my entire life.

with Malboro red or light?

Hmm, came across it while taking a toke. Waited to exhale my toke when the video said to.

That gif it broken

This video are useful. I try to hold my breath while watching and I watched several times. Hope all of you hold the breath too

Easy day💪 Glad I don't smoke.

What does the test mean if I pass?

I passed out before the video even started
