Yo Jeff ! Cold showers are a great body and mind reset. I have 2-3 10 min cold showers everyday since November 2016. Currently in the first month of winter here and I am determined to stick with the cold showers through our winter months. At 53yrs old I have noticed my surfing fitness has improved. My eating habits have changed where after a green smoothie and a green tea for breakfast I am not hungry until late evening 8pm. While it seems odd I just dont feel hungry and Iv'e shed over 3kgs in 7 months. As an anarchast thought, perhaps hot showers are part of our programming. Dig your work Jeff. Thanks.
