Weightlifters put their muscles on the line all the time, but Nick Delgado doesn’t see his attempt next week to set a world lifting record as just about his own body. For 52-year-old Delgado, it’s a vindication of his whole line of work — as president of Ultimate Medical Research, he offers consultations and supplements that promise to turn the clock on aging bodies just as he says he’s done for himself. But the event gets personal as well; his every lift will raise money for research for autism, which affects one of his four sons.
