If you have a new goal in mind or project in the works—or if you’re looking at a calendar with 365 blank days ahead—perhaps it all seems too much and you’re not sure you can handle it. I’d like you to meet Kyra Samuels, a young woman who fell in love with the sport of Brazilian jiu-jitsu. This relatively unknown sport pitted Samuels against male athletes that were stronger, taller, and 40-50 pounds heavier than she. Learn how Samuels took down these opponents, and won first place in her division in one of the sport’s most prestigious competitions, in this issue.
Also look inside for exciting developments in heart health, including a CT scanner that works faster than a heartbeat and two life-saving therapies that keep the heart pumping in some of the most dire circumstances. Also learn about concussion treatment, the big role of the thyroid gland, and some facts about back pain in this issue.
