We've covered a variety of stories this week about heroes - and different kinds of them.  On Tuesday, you learned about a teenager who founded a great cause after losing part of his legs.  On Veterans Day, we paid tribute to all of America's heroes who've served in the Armed Forces.  And on Thursday, you hear about a Pakistani custodian who reportedly sacrificed his life to protect students from a suicide bomber.

To me, all of these stories feature heroes.  How would you define a hero?
