And we don't, as humans tend to have the ability or exercise critical thinking or think about the context around what's being shown to you or told to you.

And just, and also just do a plausibility check, you know, can this be possible? Because you'll see constantly videos in this space or quick, you know, increase your VO2 max 30% in two weeks, you know, or increase your bench, you know, by some astronomical value in no time.

It's not physiologically realistic.

It doesn't happen.

And we need to have kind of a filter for what's plausible.

How fast can the body adapt? And the answer is way slower than you will be compelled to believe if you listen to all of these bro science videos you know that turn you know it i remember my son being in his bro science period you know and uh I guess all particularly teenage boys go through it.

Dad, the sports scientist, didn't know crap.

in

Dr. Seiler, there's a lot of science behind this, correct? I mean, recent science has been showing that breathing rate is actually controlled by a different part of the brain than heart rate.

Yeah, and you're mentioning the work of Andrea Nicolo, and he was formerly connected with Louis Passfield, who passed away a few years ago after a cycling accident.

And I came into it, and I was trying to understand.

I said, well, yeah, I learned in my exercise physiology courses that in a sense that breathing takes care of itself unless you have a particular pathology like asthma or you've lost a lung had a lung removed or something and that was the ground truth that we were taught in basic exercise physiology class but i think they got it wrong because fundamentally, they said, well, breathing is over-dimensioned, meaning that we have a bigger reserve for breathing or ventilation than we do for cardiac output.

And so cardiac output was seen as the limiting factor for performance and breathing was over-dimensioned.

But where they got that wrong, I think, is that Yes, if you look at it from the perspective of oxygen delivery, then breathing is over-dimensioned.

But if you look at it from the perspective of something absolutely critical, which is CO2 removal, CO2 is a poison to the body.

But if we get back to the
