Drug Resistant HIV virus

In a NYTimes article, on online responses to the public announcement regarding the possible discovery of a new mutated strain of HIV that resists all known drugs, the journalist ends with: Jon, a 33-year-old New York escort who uses the Web site Manhunt.com, a popular gay dating site, said in a telephone interview that even the most educated and cautious often slip into dangerous behavior. On Friday night, he said, an H.I.V.-positive lover he had met online came over to watch a movie. Though he worked in health care for 15 years and usually insists on practicing protected sex, this time he did not make his lover wear a condom. "After the sex, I freaked out," he said. "I thought, 'How stupid to go that route after 40 years of being negative.'" He was 33 years old? But has gone 40 years of being HIV negative? Is this suppose to be the humorous and ironic ending to the article?
