...I did forget to mention I tried the cold shower thing last year after viewing on Dr Oz the health benefits up to and including boosting one's metabolism. That was really hard for me as I usually don't even turn the cold water on when taking a shower, haven't for years, (though my hot water heater isn't set to scorching hot either) it was totally unbearable for me. I even tried slowly turning on the cold water while turning down the hot until I got it completely to cold, then see how long I could take it...I didn't last long. lol.
