But the standards, it is part of our daily. We live with them:
In the crossroads, there are traffic lights. We go at the green and we stop at the red. Et si chacun faisait comme il veut. This is not the case, as we follow a standard.
When you go to the pool, you put your bathing suit and then you go in the water. You do not do the reverse. Ici aussi, nous respectons un standard.
The surgeon, airline pilot meet standards: would you have an operation, or will you take the plane if it n ‘was not the case??
