You are so busted. Now it’s time to confess, and then apologize to the scores of kids who worshipped you; the cancer patients who found inspiration in you; your teammates; and just society in general for turning out to be such a profoundly serious fraud. You’re not a hero anymore, and unless you come forward with the truth you’ll continue to look like a coward. So do the right thing. A lot of people threw a lot of love your way over the years; now it’s time to throw them back some respect.
