Agreed - IT and medicine share the same principles of analysing, diagnosis and treatment. Both fields deal with humans. (You guys don't fix the computer/program problem - you fix the distressed person(s) computer/program/problem.)
Communication is the basis on which both these disciplines are practiced - and much can be said on that topic alone.
I like the suggestion of writing manuals/how to's - it has application in all fields.
And then farming...we have a little joke: How do you make a small fortune out of farming?
The answer: You start with a big one!
But yes, as far as fullfilment goes - few things equal farming.
