I agree because a lot of modern technologies are available and they make our dutes simplier to be done. We have more time for our families and relatives. We can be happier because we will get more love and attention from them(relatives, families). We can make a lot of new friends through internet and also we can keep in touch with old mates. Up-to-date sources make our life not so complicated and we have more free time. As for me there is no doubt that life will change for the better in 21st century.
