This is where the enigma becomes interesting. It forces us to judge by appearance: grey hair is associated with old age, while long or curly hairstyles evoke youth.
But let's take a moment to look at it from a different perspective.
An important clue: posture. Woman #4, despite her gray hair, has a straight back, smooth neck skin, and no visible signs of sagging. Conversely, the other women show slight signs of age: sloping shoulders, less toned necks…
The correct answer: woman number 4, against all odds!
Yes, it's indeed woman number 4 who looks the youngest. Why? Because her posture is upright, her skin appears firm, and above all, because gray hair is no longer reserved for seniors!
