"Early experience matters because in the first few years of life, the brain

is changing faster than it ever will again. Synapses, the connections that

brain cells use to talk with one another, multiply at first during

infancy, then are pruned back and refined, leaving only the ones that have

been consistently activated. In this way, a brain¹s circuitry is sculpted

by the child¹s experiences, positive or negative. A child¹s brain becomes

good at what it does often, whether that includes learning a language,

reading, getting along with peers ‹ or vegging out in front of the

television."

It's hard to imagine someone getting "good" at vegging out.
