It seems like people who used to work in documentary production are quite tough

Like the post about Captain Kim Seung-jin's non-powered circumnavigation earlier,
it seems like some YouTubers who used to work in documentary production go to remote places and endure extreme hardships, yet they seem to go back again without a second thought..
Usually, travel YouTubers might do that temporarily when they lack funds, but once they become successful, they tend to seek comfort in their daily lives unless they are doing it specifically for content.
It seems those whose profession was world travel or nature documentaries are fundamentally very adventurous people..
