Maybe you travel for the challenge, or just for the hell of it. Or to learn about other cultures, or yourself. Or try out a language you learned in night school. Or see the cities where your favourite movies were set. Perhaps you want to escape a humdrum life, or recover from burnout, or salve a midlife crisis. You might want to put off the need to grow up, get a job and start talking at length about house prices.

Or else you had an accident in front of the Queen like the 17^th Earl of Oxford. As Aubrey told the story in Brief Lives, with his spelling and capitalisation preserved:

 “making of his low obeisance to Queen Elizabeth, happened to let a Fart, at which he was so abashed and ashamed that he went to Travell, 7 yeares. On his returne the Queen welcomed him home, and sayd, My Lord, I had forgott the Fart”.
