- Berkshire Hathaway investing icon Charlie Munger joked that peanut brittle from See's Candies is the "key to longevity."

Want to live a long life? Maybe take a cue from investing icon Charlie Munger at Berkshire Hathaway.
"I'm eating this good peanut brittle," he told CNBC during an interview Tuesday. "That's what you want to do if you want to live to be 99," he said, holding up a piece of the sweet treat during a Valentine's Day appearance.
But not any peanut brittle will do. Munger's came from See's Candies, the chocolate maker bought in 1972 by Berkshire Hathaway boss and fellow investing legend Warren Buffett.
"I hate to advertise my own product, but this is the key to longevity," Munger said before taking a bite of his snack.
Perhaps Buffett is also a fan of See's peanut brittle as the Sage of Omaha is still working at the age of 92. For sure, he's admired See's for decades, once calling the California company his "dream business."
What's not a dream investment for Munger? Cryptocurrency.
"Sometimes I call it cryptoshit," he also told CNBC. "It's just ridiculous that anybody would buy this stuff," he said.
