Things like…
Learning to dance sevillanas from YouTube then partying it up at the Feria de Abril in Seville.
Spending a day taking random trams in Prague to see where I’d end up.
Going on a global exploration of alcohol culture whilst remaining completely teetotal (without the teetotal bit I think we probably just call that ‘backpacking’).
Swimming all the way to Japan*
*I may not have done this particular one
