Babies are born with a lot more neurons than there are in an adult brain, but the brain itself weighs about a third as much. This is disproportionately large compared to the size of the body. It continues to grow until about age 18 as more connections are made between neurons.
The eyes are also about a third of their final size at birth, but they grow faster and at six months are already two-thirds of their adult size.
Luis trained as a zoologist, but now works as a science and technology educator. In his spare time he builds 3D-printed robots, in the hope that he will be spared when the revolution inevitably comes.
