What are those interesting things that roll so amusingly under the skin? That’s what ancient Romans thought, and they named the muscle “musculus,” which translates no differently than “little mouse.” True, “mice” turned out to be very independent—in the literal sense. After all, musculature is perhaps the most underestimated organ of the human body. If you activate the muscles, at sixty you can feel like you’re thirty, and thanks to the signaling substances produced by muscles, you can become not only smarter but also rejuvenate your skin by twenty years or more. During this time, love dramas will play out on the “fat-burning factories” between proteins—reminding one of Romeo and Juliet… It’s never too late to start: to become joyful and healthy, all you need is to move your muscles!
