What will people die of 100 years from now? If you think that is a simple question，you have not been paying attention to the revolution that is taking place in bio-­technology（生物技术）. With the help of new medicine，the human body will last a very long time. Death will come mainly from accidents，murder and war. Today's leading killers，such as heart disease，cancer，and aging itself，will become distant memories.

    In discussion of technological changes，the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells（细胞） are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells，such as those of brain cells，would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100，medicine will have advanced to the point at which every 10 years or so，people will be able to take medicine to repair their organs（器官）. The medicine，made up of the basic building materials of life，will build new brain cells，heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.

    It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future.

    One of the biggest problems when we are talking is the awkward silence. Encountering this situation is so uncomfortable that you would avoid meeting new people in the first place. In the past, I struggled with this and I even thought it had to do with my DNA or something… But later I learned that once you know how to keep those words flowing, you can meet and talk to anyone you like, which helps create great possibilities for friendship, fun and shared activities that you would otherwise have missed out on.

    After studying this in depth, I had different opinions and found that one of these common behaviors is the habit of filtering (过滤)--holding back from saying something until you've "checked" to make sure that what you're about to say is cool, impressive and interesting. Another problem is not learning to get in the mood for conversation. If you don't know how to change from subjects, then it can take a lot of time to warm up.

    It is the reflex (习惯性思维) that allows you to say whatever goes on in your mind. It's fun to realize that you're allowed to say whatever is on your mind. As long as you don't say anything that could land you in jail (监狱).

    All of the "Oh! That's interesting…" "Hmm, I've never heard of that" "Hmm, cool!" expressions are reactionary (保守的) bits of conversation that prove to the other person that you're really listening. This works 99% of the time. So, if you show some interest, they'll hang around and want to talk to you even more.

    Everyone knows that stories juice-up conversations, but most people only talk about stories of their own lives. When someone mentions something related to any of them, just tell the story, even if it's not from your life. The more interesting, stranger or more frightening they are, the harder they are to forget.

    Finding a friend doesn't seem like a difficult job. However, bad friends are easier to find than good friends these days. If you're sitting there and wondering if you have a bad friend, let me define it for you.

    A bad friend is someone whose jealousies and insecurities outweigh their love for someone. They might want to be a good friend but they're too messed up in their own head to ever actually do it. They wonder if their friends are going out without them or if they're being forgotten and left behind. People who are violently insecure don't have what it takes to be the quality of a friend.

    Bad friends are narcissistic(自恋的). They look for any opportunity to bring the conversation back to them. Worse, they might not even be aware that they're doing it. In their mind, they might think they are the best friend ever, which is truly frightening.

    Bad friends are quick-change. They're by your side when you're fun and you have something to give them but as soon as you're going through a difficult time, they will become indifferent quickly. They won't bring you cold medicine. They won't give you a ride to the doctor, everything they do is self-serving.

    If you find a friend who has these same characteristics, send them to your bad friend list immediately. Your friends are supposed to be the solution to your problems, not the source.

    I believe your twenties are a time when you need positive and helpful friends. In such a time, friendships aren't easy to maintain like they once were in school. Now we actually have to put work into it, we have to make a conscious effort to keep the friendship going. You need to ask yourself, "Is this person worth it? Do they treat me like a fool or what?" if you have doubts, try to make them clear by considering the past experiences. Toxic(有毒的) friendships do nothing but drag you down. My point is that you have to take care of yourself and stop getting in touch with your bad friends. Only surround yourself with people who bring out the best qualities in you. It may sound cruel but it's true.
