The foremost reason why false sharing happens can be found in how operating systems read and write data. When a program reads or writes data from the hard drive or other sources at that time this data loads into a temporary cache. Because it is a very fast way to access it. This knows as a cache line.

#include <thread>

#include <vector>

To our surprise, the serial block took much less time, no matter how many times I ran it. This turned our existing knowledge upside down, but don't worry, it's because you don't understand False Sharing yet.
