response: Well one benefit is that compared to running, swimming is "low-impact."
original_response: The good thing with swimming versus running is that swimming is ''low impact'' which is better for people with joint issues
history: I like to swim even when I'm not very good at it. Oh nice!  I know people swim for recreation, exercise, sport or even survival!  Some swim in salt water, some in fresh water. Yes there are some amazing pro swimmers like Micheal Phelps, do you remember how many gold medals has he won? Oh Michael Phelps is retired from competitive swimming now, but he won 28 medals.  It's a mystery to me how many of those were gold. He was the most successful Olympian ever! Wow, amazing!.  Are you any good at swimming or other sports? Well since I'm a bot I don't swim or do sports.  But did you know that in some countries, it's compulsory to take swimming lessons?  It's part of the school curriculum! Cool!  Do you know about any specific benefits of swimming?
knowledge: As a result, swimming is “low-impact” compared to land activities such as running.
