Since it’s related to my book, I was fascinated by this excerpt from USA Today:

“Our brains are sensitive to stimuli moment to moment, and if you spend a lot of time with a particular mental experience or stimulus, the neural circuits that control that mental experience will strengthen,” he says. “At the same time, if we neglect certain experiences, the circuits that control those will weaken. If we’re not having conversations or looking people in the eye — human contact skills — they will weaken.”

In essence, we’re willingly training ourselves to favor online virtual stimuli more than offline real stimuli, which is madness.
