I'm 33, a SWE that sits at a computer 8hrs/day for work and then another 4hrs/day for play. I absolutely could not run five miles, but I do go for walks. I've smoked weed on and off for over a decade.
This website was absolutely trivial for me to accomplish with zero prep. I wasn't even concerned about my ability when I started - I knew the answer to be "yes." implicitly.
Surely 40s is not an indicator of strong, healthy lungs for all ages?
If you scroll down the page you can see that they are trying to start an app with 5-minute health activities.
My take on their message, "Hey, we're making an app that helps boost your health with quick 5-minute activities." is that I'd receive something like a meditation + breathwork + gratitude journaling app which, in sum, accounts for five minutes of activity, not that their intent was to increase my lung capacity to five minutes.
No one cares.
Everybody should be able to do 1:30 with some minor training. With extensive training 6m should be doable
One can put years into apnea walks and breath tables and never approach six minutes. Genetics (lung volume) and the body's ability to cope with increased CO2 levels are the critical factors.
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/exhales prior holding breath make that much difference?
I am not doing any sport or exercise, at best like <5mins per day, just walk everywhere and sit at computer most of the day.
Am I secretly the paragon of health?
I get bored more than anything else. Just did 70 seconds with one deep breath of prep. I have not sung in years.
