Look Closely At This Baby Girl. What She Holds In Her Hand Is About To Save Her Life.

While there's no alternative for some age-old remedies, there is no denying that today's technology has done wonders for modern health care.

From glasses that can literally make a blind man see to an iPhone app that can help detect cancer, we've definitely come a long way since I was a kid. However, the greatest invention of all has to be 3-D printing. It's given little kids like Rayden Kahae, who recieved a new arm, the chance to actually play like little kids and it's even helped given animals like dogs, horses and even this little duck a chance at a happy life.

Yet, it seems like 3-D printing is just getting started when it comes to more life-threatening health problems. Thanks to this amazing technology, a toddler named Jemma Starks will live a longer life than doctors first expected. Jemma was born with only half her heart and is preparing for a serious surgery, but her mom says she has one less thing to worry about, since doctors created a 3-D mold of her daughter's heart.

The 3D-printed model will help Jemma's surgeons prepare for intense procedures on her tiny heart, so they know exactly what they need to go in and can get it done quickly. Now, the doctors will keep the adorable tiny model as a trophy of one more life they've saved.
