When i read this for the first time I thougt: wow, what a crazy but cool challenge! I didn't know a lot about this so I did a little bit of research. This is what I found:
The American swimmer Michael Phelps will be swimmimg against a white shark. You van see it on Discovery Channel on Saturday 23 July. The episode will be called "Phelps vs. Shark: Great Old vs. Great White "and is described in the trailer as" the best swimmer who takes it against the deadliest predator of the ocean ".
The 31-year-old Phelps decided to retire last year after five times gold and a silver medal at the Rio Olympic Games. He is the most successful athlete in the history of the Olympic Games: split over four games won the "Baltimore Bullet" 23 Olympic titles and a total of 28 medals.
