We all do it． We all need it． Most of us need to do it for seven to nine hours a night， It is of course sleep． Many scientists believe that an average adult should get eight hours sleep per night． However， some people can live without feeling sleepy after as little as six hours of sleep． Yet， other people need about ten hours a night． Newborn babies usually sleep between 14 to 17 hours a day． Usually they only stay awake for one to three hours．
Do you take a nap in the day？ Some adults and children need to nap． This just depends on the person． One thing scientists have learned is that man is the only mammal that stops himself from going to sleep． This can be bad for our bodies in many ways． Scientists believe not sleeping enough can make us eat more and put on weight． That's right! A hormone called leptin falls when we don't sleep enough and this makes us hungrier． Hopefully you are a good sleeper and get a good night's rest tonight!

Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.
Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.
Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.
Lastly, if we can swim, we may be able to save other people from drowning. How sad it is to see a friend drowning before our eyes while we cannot help just because we cannot swim.
