Over the last several years, many major league baseball players have been spotted during the games wearing these bulky metal necklaces. I never knew what they were until I did some research on them. They didn't look like it was for any religious belief. These necklaces were used to help players perform better. It was also supposed to ease fatigue and shortening their recovery time. But how does this do all of that I ask. According to ARS technical the secret to these necklace is that it is made out of titanium nanoparticles that can help the body's own energy flow more readily. I believe that this necklace is more a placebo if anything. With all these major league teams paying high performers lucrative salaries, these athletes will try anything and anything to be the best performer on the field.
Even though the necklace really never do anything physically to their body to make them perform better, I think most of it is all in their heads.
