Thank you for sharing your thoughts, Amadeo. I think cold showers or deep diving in the Pacific ocean are totally worthy. As long as you are putting yourself in this uncomfortable position just for the joy of exploration. Good job! Thank you for bringing up “brown fat” to this conversation. As a matter of fact, Wim Hof talks about it. He called it “Brown adipose”. From what I understood is a sort of fat tissue that is capable of energy combustion. It works on the contrary of “white fat” that plays a role of depositing energy in our body. Here, check it out for more info about “brown adipose” or “brown fat”. Happy Tuesday!
