Hello! Today for this blog was free subject so I will talk about one of the things I like to do, sleep. For this blog I search some datum that I found interesting in relation to sleeping. It’s said that the human spends 25 years of his life sleeping, on the other hand it is said that sleeping a  little makes the person earn 1 kilogram a week , I also found that memories are better stored during sleep, so many times when we wake up we remember the subject better than before we went to sleep. On another website I found that lack of sleep has effects similar to those of being drunk. Finally I found a web page where it was mentioned that  sleep a little reduces the life expectancy so if I see what I have slept in since I started college I probably already lost a couple of years.
