Well... i live alone, and there is some times that i dont leave home for several days... i dont know for sure, but i would say the most time i hadnt any human contact was about one week or so...
Im pretty a loner, and i prefer being alone, so the loneliness is a good thing for me, it doesnt disturb me. Rather, is the presence of people that disturbs me sometimes.
And, friendowl, how i would like to go in a journey like yours... maybe some day i will do one by myself... anyway, i would ask you for take all pictures you can of every place you go. So, even we that stayed home will enjoy at least some beautiful pictures. And good luck! :thumbsup:
