Better nutrition and medical care early in life has allowed us to better take advantage of the blueprints within our genes. Blueprints that carry plans for just how big a healthy human being can get given an optimal environment. In terms of height, those plans rarely exceed 7 feet 6 inches.
Individuals with endocrine disorders, for instance a tumor, near the pituitary gland in the brain can experience growth that occurs more rapidly and for a longer period of time than usual. For instance, Igor Vovkovinskiy, who at 7 foot 8 inches is the tallest man currently living in America.
The tallest living person anywhere on Earth is Sultan Kösen, who at 8 foot 3 inches tall also holds the Guinness world record for largest hands and feet. But the tallest person ever officially recorded was Robert Wadlow. He was the size of an average adult male when he entered kindergarten at the age of 5. When he died in 1940 at the age of 22, he was 8 foot 11 inches tall. Andre the Giant was 7′ 4″. So in this video we discuss the possibilities of just how big and tall we humans can get.
