From Sally Satel's gripping New York Times Magazine piece on organ donation:
In the fall of 2005, I started my first online relationship. He was a 62-year-old retiree from Canada; I was a 49-year-old psychiatrist living in Washington. Beginning in early October of that year, we talked or e-mailed several times a week. This arrangement was novel to both of us, so our conversations were tentative at first, but we soon grew more comfortable, and excitement over our shared vision blossomed. After a few weeks, we decided to meet for a uniquely intimate encounter. After New Year's, the Canadian would fly to Washington to meet me - at a hospital, where he would give me one of his kidneys. Thank God.
