Until very recently, HEMS was the job that you went to in order to transition to a retirement lifestyle after spending a career traveling the world and having adventures. You'd bring those skills from all of your varied flying experience to a job that barely provides enough flight time to maintain existing proficiency, let alone learn anything. It was a good fit. It's only been within the last 10 years or so that it has become an entry level job. It breaks my aviator heart to see 30-40 year old pilots laying around an EMS base flying 100 hrs a year thinking they got the world by the tail. All those years dreaming of flying and now you're settling for that? It's a big, big world out there and more to flying than "three to go one to say no." Don't squander your flying years. They will be gone before you know it.
