I have them in my mix on a Waterproof I-Pod Shuffle called a "Swimman" see http://www.swimman.net/main.html The first time you listen to your favorite tunes while swimming laps and swimming underwater is a transcendent experience! Try it! I keep changing what I have on both of my IPOD, use a program called Limewire to do FREE downloads! My ex girlfriends son turned me on to it. I swim between 10 and 20,000 meters per week as a Masters swimmer. I love the way it makes me feel to just oxygenate that much! You can get maximum oxygen into your cells by consuming Organic Sulfur which increases the permeabilty of cell membranes, and by sleeping on a Magnetic mattress which puts a negative charge on your red blood cells so they disperse, thereby having much more SURFACE AREA for absorbing oxygen. Cancer is anaerobic and can't live in presence of oxygen. All pain is caused by some cells cry for oxygen- read The Oxygen View of Pain by Majid Ali, MD http://majidali.com/the_oxygen_view_of_pain.htm Read Ed McCabe's book Flood Your Body With Oxygen: http://www.oxygenhealth.com/ Our Masters Swim Team coach was on the Canadian Olympic team and she takes no prisoners when we do our workouts. I drink a tall glass or organic sulfur dissolved in hot water before and after each workout. My girlfiend does the same, and we both drink a lot of kombucha tea that we make ourselves. If you ever find your sex drive waning, try these things and you'll be fuckin' like minks in no time! The combo of Sulfur, Kombucha, and Oxygen is incendiary, but it also helps a lot to do bioidentical hormones so you're dialing your T levels back to what they were when you were in your mid 20s in your prime! Read Suzanne Somers book The Naked Truth About Bioidentical Hormones!http://www.amazon.com/Ageless-Naked-Truth-Bioidentical-Hormones/dp/0307237249 Suzanne Somers is 61 years old in the photo on the book cover and she could walk across any University campus in N.America and all the young studs would be wantin to jump her bones! I think it would be way cool if before our reunion all the babes in our class were to seriously check this shit out! Doin' this stuff helped me become a cradle robber. My fiance was 4 years old when we graduated in '75 and I'm lovin' it!
