Here’s an interesting fact you may have never heard of. We are significantly taller than our predecessors 100 years ago.
This was concluded in a study conducted by several health scientists known as the Non-Communicable Diseases Risk Factor Collaboration (NCD-RisC), published in the journal eLife in 2016. The team analyzed differences in height in18-year-old men and women born in 1896 and those born 1996 in 187 countries.
The lead scientist of the study, Majid Ezzati, said for the BBC News that some of the changes in height were due to genes while most of the changes were due to environmental conditions. So people are now taller thanks to improved health conditions, nutrition and sanitation.
At the top of the list are women in South Korea, who became taller an average of 9 inches while men in Iran became taller an average of 6 inches.
