The most decorated Olympian of all time, Michael Phelps, says he's officially done swimming. The gold medalist won five golds and a silver at Rio 2016. Now, he's running his own foundation, starting a swimwear line, raising a family, and working with Colgate on a water conservation campaign called "Save Water." Phelps spoke with Business Insider about his new busy schedule. Of the campaign, he said, "Like I said, I've been around water my whole life, so I basically really learned at a young age the importance of it but also one day, at one point, clean water will be hard to find." About retirement, he said, "A lot of people have asked if I'm coming back or coming out of retirement. I feel like I could swim again, but I just don?t want to."
