Some people really maintain their so well. 50-year-old Ye Wen has shocked people online for her youthful looks.
According to AsianTown, mother-of-one from China's Henan province has stunned the Internet with her flawless skin, wrinkle-free complexion and super-toned body.
She owes it to swimming.
A photo of Ye at 30 years ago shows her looking visibly more haggard and thin.
Whereas at 50, she looks way better and has a body that would put 20-year-olds to shame.
The woman, who has an adult son, said she started swimming when she was 30 and became interested in keeping fit.
She took her hobby one step further in March, swimming across the straits of Malacca, according to the report.
And she is also hoping to swim the Han River in South Korea.
Ye said she trains daily at her local swimming pool and keeps toned by heading to the gym two to three times a week for two hours.
Her hope is that she will be able to keep wearing a bikini even when she is 80.
