According to the authors of the study, based at Imperial College in London, genetics are not the sole factor in determining height variation among different nations, as Majid Ezzati, lead scientist of the project explained: "Genes don't change that fast and they don't vary that much across the world. So changes over time and variations across the world are largely environmental." Of critical importance were sanitation, healthcare and nutrition, he said, as well as the mother's health and diet during pregnancy.

Other surprising findings, relating to how height impacts on people's health and income, have been revealed. For example, tall people can expect enhanced longevity and they are less likely to suffer from heart disease. Tall people are also likely to earn more! According to research by Exeter University, a British man who is 7.5 cm shorter than his counterpart will earn £1,500 less!It might be time to invest in a pair of shoes with heels!
