身高和体型并不是一个人的价值，但个子高的人在特定的方面可能占肯定的优势。纵览历史，人类是不是越长越高？
How tall are you? Do you tower over your friends and family or are they people you literally1 have to look up to? Obviously, were not all the same, and size doesnt really matter. But did you know that theres a possibility that were all getting taller?
Of course, our height is out of our control its a biological fact, influenced partly by genetics. The idea that being taller gives you more power and authority might be a tall story, but according to David Robson, writing for BBC Future, on the basis of first impressions alone, taller people may have the edge. He adds that despite some slight risks to your health, various studies have found that the greater your height, the higher you score on measures of happiness and enjoyment3 of life.
If this makes you want to become loftier4, its good to know that all of us are taller than we were 150 years ago by as much as ten centimetres. Scientists have known for a long time that humans with good diets and reliable access to food tend to grow taller and mature more quickly. Adult height in some countries has rocketed as they transformed into a developed society.
In a recent study, scientists have discovered a brain receptor, called MC3R, linked to our growing process. Its thought to be the crucial link between food and sex development and growth. Professor Sir Stephen ORahilly from Cambridge University told the BBC: It tells the body were great here, weve got lots of food, so grow quickly, have puberty soon and make lots of babies. This discovery could lead to drugs to improve muscle mass and treat delayed growth, UK researchers say.
For those aspiring5 to be taller, we need to look at the Dutch, who stand head and shoulders above the rest of us as the tallest people in the world. But there is a ceiling for height, and its reached when people achieve their genetic2 potential. But, of course lanky6 people have to stoop through doorways7 and struggle to fit in cars and can have joint8 and cardiovascular problems, so maybe we should be careful for what we wish for.
