Neuroscientist mostly agreed that there is no agreed-on benchmark, that a brain is fully developed. However, it is safe to say that brain is continuing to developed well past at the age of "18". Brain development happen in different stages and all in varying times. Brain consist of gray matter and white matter. Gray matter grows as we learn, as puberty sets in, our brain starts to prune back some of the gray matter, and produces more white matter, to share information better and faster. Overall most neuroscientist agree that, there is no magic age at which the brain reaches adulthood, but about age 22 or 23, the brain is pretty much done developing.

Explanation:
Elie Weisel's memoir "Night" is about the persecution of the jews by the Germans during the worst genocide in world history. The events leading up to the Holocaust and the resulting after-effects through his personal experience provides one of the most prominent witness accounts of the crime.
When Weisel states that <em>"lying down wasn't an option</em>", he reveals how congested space was in the cabin. The <u>"lucky ones" were able to breathe in the fresh air from the window, while the rest have to be satisfied with wherever they are.
</u> This reveals his realization of the grim situation inside the over-packed cabin, where there is hardly any space to move.
And when he said that they <em>"never ate enough to satisfy our hunger"</em>, he presents the realization and understanding of the grim situation in the train's cabin where eating is not a luxury, but a necessity to stay alive. And for that, they know they have to <em>"economize, to save for tomorrow"</em> rather than just stay full once.
A single pulley changes the direction of the effort, but it has
no mechanical advantage. The output force is the same as
the input force, so we'd say that the mechanical advantage is 1.
If there are two pulleys, with the rope going up and down and
around between them several times on its way from the effort
to the load, an arrangement that I think is called 'block and tackle',
then the mechanical advantage turns out to be the number of
strands of rope that are supporting the load.
