Hello! Welcome to steemit :D
... in the winter I swim in cold water.
Oh my, I can't put my nose out of the window in winter O_o Thinking of cold water, even in summer freaks me out, but swimming in cold water in winter - instant death :D How did you train yourself to do that?
You can't think when you are coming into the water;) You need to do it quickly and stay there for a few minutes! And next time prolongue this time. It's easy;)
