Brave 6-year-old boy saves younger sister from dog attack.

This brought tears to my eyes when I saw that Bridger Walker, a brave 6-year-old boy who protected his younger sister by shielding her from an attacking dog. He said "If someone had to die, I thought it should be me". Bridger received 90 stitches on his right cheek from the dog attack. There has been an outpouring of support from celebrities including "Captain America" Chris Evans who is sending Bridger a signed Captain America shield. This young man is a superhero.
