Well... not specifically, but I've met lots of health professionals enjoying life while making a living out there. Dentists, especially.
As for me... I abandoned all career pursuits when I left Hawaii 12 years ago on a 37 ft pilothouse sloop. The boat was paid for and I had no debt or credit cards. I did have pieces of paper, tools and skills which enabled me to eek out a living as a boat captain, commercial diver & canvas maker. Plus I had a job waiting for me in Saipan, driving a sunset dinner cruise boat. After growing bored with that I sailed to Guam and scored a job on a dive boat before I'd even cleared customs! I stayed real busy with that for several months and then headed south for Australia... where I picked up a casual job selling helicopter rides to tourists out on the Great Barrier Reef. Sweet. The office was in the marina where we were berthed and I made pretty good money without having to wear shoes. I was in Ozzy long enough to earn a captain's license there, too. Next I wondered north thru Papua New Guinea and earned a few Kina tinkering on neglected boats, generators & trucks at several resorts which often provided dock space, showers, electricity and facilities for working on my own boat, too. I hauled out for two weeks in Madang for less than $200.USD and didn't even have to get my hands dirty! Then back to Guam for a 2 1/2 year period to focus all my efforts on fixing & upgrading the boat, topping up the cruising kitty and (best of all) getting married... aboard our boat, naturally. Now - my wife is certified as a scuba instructor and teaches English as a Second Language... whenever the opportunities present themselves.
For us, the trick has always been to wander a while and then stay a while, in distant places. Finding jobs along the way has never really been a problem because (in my opinion) the "talent pool" is quite shallow in remote places and finding employment is pretty easy, so long as you're honest and willing to work... and (especially) willing to share what you know. The world will open it's arms to you if you're polite, sensitive to and abide by local customs. Try to refrain from romancing the local cuties and above all DO NOT BE AN UGLY AMERICAN.
We'll never really make a lot of money - but now, after 12 years of gallivanting around our watery world, we've come to learn how little money we really need.
Elliott, I've seen domesticated animals EVERYWHERE and as a Veterinarian, with a simple bag of tools and the right frame of mind, well... the World can be your Oyster.
I'd like to chat longer but the Olympics are on.
