詞匯: growth 生長發育

How tall are you? Do you tower over your friends and family – or are they people you literally have to look up to? Obviously, we’re not all the same, and size doesn’t really matter. But did you know that there’s a possibility that we’re all getting taller?

Of course, our height is out of our control – it’s 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 AYYBLOG 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 enjoyment of life.

If this makes you want to become loftier, it’s 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. It’s thought to be the crucial link between food and sex development and growth. Professor Sir Stephen O’Rahilly from Cambridge University told the AYYBLOG: “It tells the body we’re great here, we’ve 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 aspiring 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 it’s reached when people achieve their genetic potential. But, of course lanky people have to stoop through doorways and struggle to fit in cars and can have joint and cardiovascular problems, so maybe we should be careful for what we wish for.
