There has never been a professional athlete to live past 100. When you sweat, you sweat out everything that’s in your blood stream. All the essential nutrients vanish. If not replaced the “fit” sweaty human will become deficient in many of the essential nutrients. These athletes will also experience a breakdown of joints, tendons, ligaments, cartilage, connective tissue, and bones. After laying down the info on essential nutrients in past posts, I assume you all know how bad being deficient in minerals can be. You can’t utilize vitamins, enzymes, and other minerals without certain mineral cofactors, among many other things… You’d be running with no oil. It’s been said, exercise without supplementation can take off 20-50 years off your life. Many young athletes have collapsed, and never gotten back up.
