Gene Weldon, 34, was praised by friends and family Monday for his expertise on dog breeding, spelunking, and countless other subjects except leading a normal life. 'One time, I asked Gene what he thought about the recent market fluctuations, and he gives this long lecture on the history of the Nikkei Index,' friend Mindy Becker said. 'With a body of knowledge like that, you'd think he'd at least own a car.' Cousin Mike Framisch agreed, saying, 'For a guy with no regular full-time job, he knows an awful lot about the ecosystem of the Marianas Trench.'
