Show HN: Can You Hold Your Breath for 40 Seconds?

Is 40 seconds... challenging for people? Sorry, I don&#x27;t know, maybe this comes off as entitled.<p>I&#x27;m 33, a SWE that sits at a computer 8hrs&#x2F;day for work and then another 4hrs&#x2F;day for play. I absolutely could not run five miles, but I do go for walks. I&#x27;ve smoked weed on and off for over a decade.<p>This website was absolutely trivial for me to accomplish with zero prep. I wasn&#x27;t even concerned about my ability when I started - I knew the answer to be &quot;yes.&quot; implicitly.<p>Surely 40s is not an indicator of strong, healthy lungs for all ages?

Thats quite a good marketing trick actually. Something that most people can do and probably would do. Getting them to buy in do the small excercise and then going to the sign up. Well done to whoever thought of this.

Blacked out, woke up only to find myself subscribed to numerous activities

I can do 3:30 and I even submitted a short film about it to a local film festival. People still thought I cheated somehow.<p>Everybody should be able to do 1:30 with some minor training. With extensive training 6m should be doable

Does holding your breath mean “don’t exhale” or “don’t inhale”?

Thank you for not choosing 50 seconds because 40 about killed me, and I am very stubborn.

I thought it was easier when I closed my eyes and didn’t think about the time (just treated it like meditation). If I had my eyes open and saw the countdown, I kept just trying to want to breathe.

I can do about 2:36 when I tried it recently sitting at kitchen table, zero preparation besides few deep inhales&#x2F;exhales.<p>I remember without any preparation in past I could do 50-70 seconds, so I was blown away by 2.5 minutes after many years, do those few deep inhales&#x2F;exhales prior holding breath make that much difference?<p>I am not doing any sport or exercise, at best like &lt;5mins per day, just walk everywhere and sit at computer most of the day.

I have ~always been able to hold my breath for multiple minutes. I am very un-fit and have been for most of my adult life.<p>Am I secretly the paragon of health?

I only see blank page; however, this seems similar to BOLT score. However, there is something called the bolt score. Here is how to measure and where I learned about it (oxygen advantage book):<p><a href="https:&#x2F;&#x2F;oxygenadvantage.com&#x2F;measure-bolt&#x2F;" rel="nofollow">https:&#x2F;&#x2F;oxygenadvantage.com&#x2F;measure-bolt&#x2F;</a>

Who is liable if I have a medical issue while taking your test? Nice sales tactic though!

pleased that yes I can but only just, what is the significance of 40seconds?
