Toward the end of the world, human height is reduced gradually. true or false?

Correct! One reason is because kids/ our next generation is not getting the nutrients they need and not enough calcium. Rather, they are increasing their amount of caffeine, and as people know, caffeine makes a human body stop growing. That means they will be shorter. 

Help save the next generation! Less caffeine and more calcium! :D

True!
This is because of how unhealthy people are now adays, just think about the future.
Caffeine plays a major rule in this.
Starbucks, Dunking doughnuts, and more. The more caffeine people have, the shorter they get as they grow older.
