Humans have been shrinking for 6000 years. Did you know that, when life on Earth began 6000 years ago humans were huge?

Most humans stood around about 150 feet high. The reason for this was because the air was much thicker and humans lived for around 600 years at that time. It is just as well the first humans were so big otherwise we would not have defeated the dinosaurs and had they won...Well, dinosaurs would now be in charge of the Earth.

Food for thought.

I may be a naturally tall person, but there are many who are much taller than myself.

According to the Guinness Book of World Records, the world's tallest human was a man named Robert Wadlow Pershing, who measured at a staggering 8 feet and 11 inches.

And compared to the average human height, that's very tall.
