Great article. I'm not sure I buy into the idea that everyone is afraid to do it, but I admit that fear can be a factor. I think for some, especially the type of traveller that's more into resorts than exploring local life and culture, that a full year of travel will make them vulnerable to those moments where they will miss the comforts of home: sleeping in their own bed, family or friends, or even some of the old routines.
Travel is great... one of my favourite things to do. But it can be a stressor as well when things aren't going too well. Days feel longer, more frantic. I don't think it so much as fear as an occasional mental longing for the comforts and familiarity of home.
Great read though, you have my upvote.
thank you for your kind comment. Yes, fear is a big factor for the people, fear about the unknown ...
