has practical applications: in the future doctors could see through their hands or other obstacles when they are doing operations. G. An amazing new sofa has been invented by a group of scientists in Northern Ireland. As soon as you sit down on it, it will know it's you. The sofa is connected to a computer and weighs you when you sit on it, then it checks its memory and decides who you are.

I do not think parents need to live together if they do not like each other. If they do not like each other - they are unhappy. Divorce is always very hard for people. Marriage contract allows a party to protect themselves in the event of a divorce, but will never return the love. Parents and children can and should understand each other, because they are the closest people. To build mutual relationships between children and parents, we need only love on both sides. The biggest problem in family life - is a mutual understanding, patience and hope.
