The most interesting thing is that for this you don’t need to rush somewhere, trying to catch up with the rotation of the Earth around its own axis! It was possible to meet the new year 2000 two or even more times, practically standing still! To do this, it would be enough to arrive in advance at the border of any two time zones. Having met the New Year one step east of this border, you can safely take this step west, return to 1999 and an hour later congratulate yourself again on the holiday. And you can also walk through the border of time zones back and forth as many times as you like during this hour, while constantly moving from one year to another.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
