Whenever the noise becomes too much, I can turn it off. All it takes is a press of a button. Or, even better, I remove my earpiece entirely. Sound is now off.
This silence is the most absolute that any human can experience, one beyond the best noise-canceling headphones or earplugs. It’s a tranquil state of being, as if I were at a deserted lake on a windless day: still and serene. I do my best thinking here, shielded from the noisy world.
