Two cool things I noticed when watching The Olympics:
(1) The fastest man in the world getting "adjusted" by his chiropractor. This is cool, it shows that this service isn't just for pain, but for performance. You don't need to be in a car accident to get your musculoskeletal system checked, and you may want to get checked just to get the upper "edge" against the competition.
(2) The k-tape returns to volleyball! The first time I saw k-tape was at the last summer olympics when USA's female beach volleyball team was all taped up in pink. "That's weird... probably nonsense." It wasn't until years later, when I had a sprain in my leg from running that I was able to experience how "magical" (Lance Armstrong called kinesio-tape "magic" tape) this tape was for myself. If you're an athlete, find someone who is experienced in k-tape application, and test it for yourself. It works. (Want to know some of the "How" it works, this man wrote a great article about it here) You really should experience it yourself next time you've got an injury.
Keep watching The Olympics, take notes. These are some of the fittest human beings on the planet, see if there's anything you can change in your own life to treat yourself like an Olympian.
