Why do you go to bed at night?

Answer 1

We go to bed because if we don't, then we won't have enough energy the next day. But if you're wondering why we go to bed when it's dark outside, it's because it is no use going anywhere at night because you can't see anything and also it is more peaceful when there are no cars going down the road while you are sleeping. (Except if you live very close to the road)
