Recently I read a report that scientists are trying to figure out a way for humans to remember everything and they have made a big progress.However,I really wish that they will never succeed.It's ture that there's an awful lot of things that we try not to forget,sure that you can pass exams easily if you never forget.But for something ,it's better not to remember.I've read about some people who can remember everything they went through,however,the amazing capacity is proved to be an disaster,because they remember everything,every mistake every hard time,every pain,they just repeat over and over again as clearly as they are really happening.Maybe we live happier without a strong memory,don't we?
