Can you guess who is the youngest

This riddle is not just for fun. It reminds us that we are often influenced by visual clichés:
Gray hair = old person? → Not necessarily!
Firm skin and straight posture = youth? → Often, yes.
Appearance = truth? → Not always.
And you, did you guess the right answer on the first try?
Or were you fooled by the obvious? Either way, this riddle encourages us to look at things differently, to go beyond our automatic assumptions and to question what we take for granted.
A valuable lesson in observation… and humility!
