If I didn't have to finish my degree and get working I would live out my life as a hermit...
I think you can't be a hermit 100% and not losing your mind. Because we need mirrors to see ourselves. I think we cannot know who we are without touch with other people.
You become a hermit when you lose your mind (in a good way)
As long as they want. I've done it for 5 and still going.
Being on the internat already contradicts your statement dude.
