💨 Abstract

It seems you provided two different articles in your request. I'll summarize each one separately. **Summary 1 (the shark swim):** 62-mile, 12-day swim around Martha's Vineyard in cold water by Lewis Pugh to raise awareness about white sharks. This reveal coincides with the 50th anniversary of "Jaws", aiming to change the public's perception of the animals.
