A 23-year-old man got his finger caught in an envelope converting machine at work in where two two cylinders were spinning the same way.. CrossFit was his saving grace..his improved blood circulation was related to his body's ability to heal better..otherwise he would have lost his finger completely... In emergency doctors have placed 7 stitches n sent him on his way...the wound healed completely up over one year... Now he has full use of his finger!!
