A cleansing bath for the first Sunday in the New Year, perhaps? Ed tried to talk his friend into jumping in ("Tried to persuade a friend to jump in by offering to buy him all his drinks the next weekend. Didn't work.") Ah, the life of a traveling college student.
The Roman Baths at Bath do look really amazing. It's ALWAYS tempting to want to jump into baths/pools/fountains at many famous and historical places where you know it was commonplace to do so in the past. I think of the fountains at Peterhof Palace outside St. Petersburg, Russia; the Neptune Pool at Hearst Castle in San Simeon, California; the Jardín del Estanque in the Alcazar in Sevilla, Spain.
Whatever your cleansing ritual for the New Year, jump to it!
