Scientists Vindicate Phelps, Lochte on Pool Urination
Many water-related stories have been in the news of late – including reports connected to the three questions below.
1. Following the 2012 London Olympic Games, U.S. swimming champions Michael Phelps and Ryan Lochte both revealed they urinated in the Olympics training pool — and they asserted there was nothing wrong with the practice. That assertion has been validated by the organization Sense About Science (SAS), at least when it comes to health concerns. Each year, SAS “challenges and examines scientific claims made by celebrities to prevent inaccurate information [from] gaining public acceptance….” Why did the group say Phelps and Lochte were right?
a. In a large pool, a single urination is just “a drop in the bucket.” b. Urine — a combination of salts and water, with moderate amounts of protein and DNA breakdown products — is essentially sterile. c. Chlorine in the pool prevents bacteria from growing anyway. d. All of the above.
2. Despite several attempts – her most recent at age 63 – American open-water distance swimming legend Diana Nyad has failed to achieve her dream of swimming from Cuba to Florida without benefit of a shark cage. Now 27-year-old Chloe McCardel, also an accomplished open-water distance swimmer, has announced her intention to attempt the same feat in 2013. What country is McCardel from?
a. Canada b. New Zealand c. Australia d. Ireland.
3. Openwaterswimming.com has conducted a survey to determine the number of people engaged in open-water distance swimming. How many professional open-water distance swimmers are there in the world, according to the survey results?
a. 379 (203 males and 176 females) b. 491 (300 males and 191 females) c. 785 (395 males and 390 females) d. None of the above.
