If you're going to get sick, Houston is one of the best places in the world to be. Along with oil and space, medicine has put Houston on the map. The Texas Medical Center, the largest concentrated center of its kind in the world, is at the forefront of cutting-edge treatment and research, and other hospitals and treatment centers around the city offer the latest breakthroughs to patients seeking the latest advances in medical care. During the month of July, CultureMap highlights what's happening in the ever-changing field of medicine in Houston. Our special editorial series features interviews with many of the city's medical leaders to assess what is happening locally and around the world in the field of medicine. With so many changes on the horizon, we ask the experts to explain the challenges of health care coverage and offer solutions. We also take a look at the heart, with some startling images of how our risky lifestyle habits do lasting damage, and examine what's going on at the Memorial Hermann Texas Institute for Rehabilitation and Research, which has garnered so much national publicity as Arizona Congresswoman Gabrielle Giffords continues her remarkable recovery.
