Fabrice Muamba did...

(CNN) — Devastated, but grateful to be alive — soccer player Fabrice Muamba announced his retirement on Wednesday, five months after suffering a cardiac arrest on the playing field.
The 24-year-old, who played for English Premier League club Bolton Wanderers, collapsed during an FA Cup match at Tottenham Hotspur in March.
Medics battled to resuscitate the midfielder in front of the White Hart Lane crowd and it was later revealed the Zaire-born player's heart had stopped beating for 78 minutes.
Fabrice is really a dead man walking.
