Hello again Manu. I can now give you a formal welcome on behalf of the sailors here on the Anchorage.
From your resume, I think you will fit in very well with most of us here. It seems as if the majority of us have dabbled at one time or another in all those hobbies that you mention, although I don't recall any actual critical care doctors. That role would make you very popular indeed on any warship.
I expect a few of the crew will be along shortly to give you their own brand of welcome.
Till then sail safe with a fair wind behind you.
Rob.
