Science and its blessings cannot be overstated. Science technology is changing with the changing times. In the old days, people could move from one place to another with ease. They did not have to fear any external danger. However, there was no means of communication to inform the family in case of any loss. Now that thinking has changed. Because now the people of the outside world are not as simple as before. They can do you any harm for their own sake. Even your family members are not safe.
