Superhero fanatic

I am a superhero fanatic. I grew up reading about these characters, admiring them, and occasionally dressing up as one of them.

In particular, I like the Man of Steel, no other than Superman, and Iron-Man because of their superhuman strength, extraordinary powers and virtual invincibility. 

However, there is a deeper reason other than those I mentioned that made me like these two characters. Try and guess it... heh-heh-heh.
