My older son and his family took a vacation to Norway in the winter and became a believer after taking a cold water plunge . He does jiu jitsu and is in the prime of his life but always looking for better health through diet and exercise . He bought a freezer and some apparatus and made a ice cold water plunge and a one person steam sauna to boot . It is becoming the latest craze and thought to discuss more of it on this cool forum .
