If being in the on a deserted island means having no civilization, then a single person doesn't constitute civilization. So, the on a deserted island means having to survive however you can, without company. Well, nature, water, and animals keep you company, but I don't think they're very sociable. Neither am I. So, being in a place like this might not be too boring for me, but only for the first few months. After that, I don't think I'd feel right without hearing other people; at least listening to them, not socializing.....
I'm a strange man, yes, I admit it
