TikTokers all over the world are going viral after sharing their results from the “Mental Age” quiz.

But, what is it and how do you take it yourself? Since its creation in 2016,

 TikTok has been the hub for viral content with new trends and challenges

 spreading to For You Pages around the world. Another thing that 

TikTok users love is any type of personality test that pops up,

 like the human feeling quiz and the multidimensional anger test. 

The latest quiz to go viral on TikTok is the ‘Mental Age’ test, 

which tells the user how old they are mentally, or rather, 

how old they ‘act’ based on their interests. The Tik Tokers quiz taker begins 

the video by saying "I'm __ but my mental age is..." before moving on to the quiz results.
