This may sound presumptuous, but I'll bet Charles Krauthammer is a far bigger man today than he would have been if he had never been disabled.
And I am willing to agree with you. My own father was paralyzed at the age of 37 and he wasn't expected to live 24 hours. He lived 9 yrs. You never saw such determination in a man. I have witnessed firsthand the inspiration that these people give and the desire they have.
All who can walk normal should count our blessings.
