可以预测孩子未来身高的简单公式
Would you like to know if your child is set to stand head and shoulders above the rest? Or if they're likely to stay diminutive into adulthood?
想知道你家孩子将来的身高会鹤立鸡群吗？还是会一直这么矮下去？
There is an easy (although fallible) mathematical equation that can help you predict how tall your child will be.
The formula, which has been used since the 1970s and was revealed in the New York Times, predicts that 'most (but not all) children will reach a height somewhere within a fairly small range that can be estimated by the average combined heights of their parents.'
How does it work?
BOYS
Add the heights of both parents plus 5in (13cm) and divide by two.
GIRLS
Add the heights of both parents minus 5in (13cm) and divide by two.
These predictions are by no means completely reliable, however, as environmental factors such as nutrition play a big part in determining human height.
