Owswimming.com recently conducted a poll to explore how swimmers from different countries defined “cold”. They have posted the results on their blog and you can check it out here.
“When I showed these results to my fellow swimmer (and wife) Susan, she said “Duh, so swimmers from cold weather can stand colder water”. Well, it is true that I am not solving the Riemann Hypothesis, but I kind of like having data that supports anecdotal assumptions.”
