The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
So if you've heard the exercise increases the number of neurons in your brain, well, that's not true. And that probably is a good thing, frankly because we always hear more neurons, more neurons as if it's a good thing, but the brain doesn't do so well with bringing in entirely new elements.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

It turns out increasing the number of neurons may not actually be as beneficial as we think. It all sounds great. More neurons, more neurons. Certainly more neurons is better than fewer neurons and losing neurons, but incorporating new neurons into existing brain circuitry is actually very challenging for the brain to do.
