Yes.

As a point of interest, the English do have a sort of stiff upper lip thing going on since forever. It's normal in English upper class families to send kids to boarding school. This was partly enabled by empire, but seems to have persisted. I have English friends who think nothing of living on another continent to their children.

On the mental bearings of extreme travelers, I used to do some long distance (multi-week) cycle touring and offered accommodation to others through platforms for this purpose while living in China. They say you have to be half-mad to get in to cycle touring in the first place. Some of these people were very much in a weird mental place. After a bad experience with a German woman I stopped participating in these systems. Some of them would turn up broke with no shoes really in need of help. A subset of the people who finish go on to become motivational speakers. Most of them probably wind up happy, but grizzled and impoverished with more physical than mental health.
