As someone who travels a lot, I can assure you I'm the ultimate authority on this
  1. To spread your syphilis even farther than Captain Cook spread his
  2. To find a grocery store that doesn't carry peanut butter and then you have to try and explain in a language you don't speak what peanut butter is and then ugh just give up
  3. Contrast and compare prisons in person
  4. Regale tinder dates with the various worldly diseases you have contracted
    I've had dengue fever!
  5. That's it, all the reasons to travel. The end!
