I'm sure you all know about this heroic young Romanian boy, but I think it's worth reminding ourselves of his bravery.
The 13 year old (or 15 year old, depending on source) Christian Becheanu offered to go down a narrow pipe to save the small child who had fallen into it. What a wonderful act of selfless bravery by one so young and seemingly fearless. He is awarded 'The Cro Medal for Gallantry'.
This was in 2013; he must be about 24 by now.
