It used to be a matter of fact when Peter Pan—a character from James Matthew Barrie's 1911 book—said:“All children,except one,grow up.”1.

According to the NPD Group,a US market research company,sales of toys to adults in the UK increased by more than 20 percent in 2016,three times the pace of the children's toy market itself.These toys ranged from puzzles and Lego building sets（乐高积木）to vehicle models and action figures.And more than half of the sales came from millennials—people born between the 1980s and 2000s.“Adults of the 21st century are channeling their inner child, one toy at a time,”commented website Koreaboo.2.According to Frederique Tutt,all analyst at NPD,the motivation of these grown-ups is to escape the stress of today's fast-paced world.3.“It reminds me of the playful side of life,”Rob Willner,a 25-year-old PhD student in the UK,told The Telegraph when talking about his love for Lego,which he said brings him both comfort and entertainment.

4.To Frank Furendi,a professor at the University of Kent in The UK,the fact that so many adults are pursuing "the thrills of youth" is the evidence that "adulthood has got nothing attractive about it anymore",he told The New York Times."That's actually quite sad."

5.According to Canadian comic book artist Todd McFarlane,collecting toys could simply be a way for people to express their individuality."It's just pop culture stuff.It's stuff that says,I like a little of this and I like a little of that,"he told ABC,News."It's no big deal."So now that over 100 years have passed since Peter Pan,perhaps it's time to introduce a new "fact",as stated in the tagline of the UK fashion brand KIDULT:"Growing old is mandatory（强制性的）,but growing up is optional."

A.But scientists are probably just worrying too much.

B.Why do these kidults turn to toys for pleasure and comfort?

C.This is also why these adults are sometimes referred to as "kidults".

D.They are driven toward the more immediate pleasures brought by toys than those brought by,say, getting a promotion,which is far less easy to achieve.

E.The scientists are concerned that those kidults show roo much individuality.

F.But this "fact" doesn't seem to apply to today's world anymore.

G.Despite this,some social scientists see the trend as disturbing.
