Studying at an earlier ages and at the age of 7

It is true that in the world there are 8 billion population and nobody has similar concern about getting knowledge. Some people hope that best period to do this is between 3 to 6, while others hope that in this period child should play with peers. And I agree with the first groupg's opinion. Some parents in order to protect their child do not allow to them play with peers or go to the kindegarden before school. Unfortunately, this child in the future will not able to not only to communicate with others but also expres ideas to sosiety and these are drawbacks. Hovewer, these children at home before going to school can learn languages or do sports with parents or sibling and these are advantages. Fortunately, some parents and I prefer to earlier ages to study. It is scientifically proven that best ages for individual to study begins since 3 to 6 years old. It is firts phase in our life when we get essential as called 'concrete' knowledge as well as in this ages parents use all opportuniy to help child to become 'hero of his time. And parent's all effort and devotion become a fruitfull result in suibsequent years and child will understand that parents helped to cultivate abilities before going to school. All in all for the better future of child I advice to parents to teach their son or daughter in earlier age before going to school and before identifiying dark sides of life.
