And if you are over 30 years old, then you will “crunch” automatically. But in this matter you need to be very careful. There have often been cases when such a seemingly completely harmless action led to very sad consequences. For example, in 2019, 23-year-old Briton Natalie Kunitsky simply stretched her neck while watching a movie while lying on her bed. As a result, her entire body became paralyzed. It turned out that she seriously damaged the vertebral artery, and this, in turn, led to the formation of a blood clot in the brain and a stroke. Doctors performed surgery but were unable to remove the blood clot. The left side of Natalie's body remained paralyzed. This is such a creepy story! And the author of the video kindly showed us how to crunch the body correctly. Remember.
