His résumé grew to include tennis halls of fame, Fortune 50 boardrooms, and speaking about chronic disease prevention before the United Nations.But behind the accolades was a man unraveling. Failed marriages, estranged relationships, and a hospital stay with no one by his side revealed the emptiness of a life lived for trophies and applause.
