Express Action Sports

I’m thinking about either emergency medicine, sports medicine, or hematology, but I’m really open for anything. What are some possible fields of health that are looking like they have a bright future? I would consider any medical job that requires action, a sense of making a difference, but also a job that would be secure for years to come. Thanks.

I will plug my own, forensic pathology. Good hours, pretty good pay, no insurance company hassles, some real answers, research and teaching possibilities, constant learning, incredible job security.
