"This is a tough question because many breakthrough advancements and inventions have occurred in the past 50 years. However, I am most fascinated with 3D printing. I find it amazing that orthotics and prosthetics are created using 3D printers, and now researchers are looking for ways to print whole organs. What's exciting about 3D printing is that custom-tailored implants and personalized prostheses can be made for patients undergoing rehabilitative therapy. I'm excited to see what the next 50 years have in store for the medical industry!"
