How do you keep quiet:
I go to a fitness club and you know, I discovered an interesting fact - a lot of people are engaged in sports hats with hats on their heads. And I want to ask... why? ... Intentionally...? Do you have a cap on the runway? The idea is one – under these very caps they have caps made of foil, so that the foil could significantly reduce the intensity of the exposure of high-frequency radiation to the brain.

In the cardio zone, there is usually strong ventilation. If you exercise intensely for more than 30 minutes, the wet head begins to freeze.
I like to imagine myself as Rocky Balboa.
