"I'm a hero with coward's legs"

This quote by Spike Milligan is a reflection on the idea of heroism and courage. It suggests that although one may have the heart of a hero, they might not have the physical strength or nerve to act on it. It suggests that although one may have the desire to do brave deeds, they might not have the courage to really do them. This quote might be translated as a tip that nerve is not constantly physical, but can likewise be psychological. It might also be interpreted as a tip that nerve is not always about physical strength, but about having the self-control to do what is right. Eventually, this quote is a tip that guts is not constantly about physical strength, however about having the self-control to do what is right.
