这个公式能帮你预测你家孩子身高
How tall will YOUR child be? The simple formula that can predict how big your kid will grow
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.
有一个简单（但不一定靠谱）的数学公式可以帮你预测孩子未来的身高.
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.'
该公式自上世纪70年代开始流行,发端于《纽约时报》.公式称,"根据父母的平均身高总和,可以推算出孩子身高的波动范围,这个波动范围很小.大部分（并非所有）孩子适用这个规律."
How does it work?
具体怎么算呢？
BOYS
男孩
Add the heights of both parents plus 5in (13cm) and divide by two.
父母身高相加,总和再加5英寸（13厘米）,用结果除以2.
比如父亲1米76,母亲1米65,那儿子的身高就是（1.76 + 1.65 + 0.13）/ 2 = 1.77,即1米77.
