If you look younger than your age then fair play. It's an admiration of many. Many who would have to blow the dust off their IDs because, frankly, youth left them behind a long time ago.
For the majority, IDs remain in the wallet after they've reached the age of 25. But one mum, who is three-and-a-half times the age of 18, still looks young, as do her two daughters.
Sharon Hsu, a 36-year-old actress from Taiwan, shared a picture of herself, her sister, Lure (41), and her 63-year-old mother - who remains nameless.
Can you guess which one is the elder?
Well, she's the one in the middle. Dressed in a white lace dress, flower-adorned waist belt and make-up, she stands were her two daughters either side.
It is that wrinkle-free look (lucky bugger) and trendy outfit that has caught the attention of social media users.
The Instagram snap featured the caption: "Dear Mommy! Happy Mothers' Day! Just hope you're safe and healthy! We will always love you!"
Commenters were quick to point out how young the mother looked.
"Mum seems too young," said one, while another asked which one she was. "Oh my God, mommy too young," stated one user, while one comment read: "Mother so young, it's beautiful".
Clearly, the good looks run in the family genes, as neither daughter looks their mid-thirty, early-forty ages either.
Earlier this month, Lure, an interior designer, similarly wowed the internet with her teenage-esc looks.
During an interview with Taiwan's Friday magazine, Lure revealed the top secrets to her youthful looks were drinking water and eating vegetables - with the former the most important.
However, when you think about it, who does the compliment affect more? The daughters for looking older maybe, or the mother for looking young?
Natalie Wardell, 45, of Australia, caused a stir when pictures showed how similar in age she looks when compared to her two daughters, Jazmyne and Tamika, who are 21 and 19-years-old respectively.

Speaking to the Daily Mail, Natalie said: "People ask if we're sisters all the time, and some even think Jazmyne is my mum because she's so tall and I'm so short." Jazmyne must be raging at that line!
