A woman is having a massage at the Lukacs Bath in Budapest, Hungary June 28, 2016. Hungary's capital owes its popularity as a tourist destination partly to its numerous hot springs and bathing culture which have drawn visitors to the area since Roman times. Bath houses range from large, ornate 19th-century buildings like the Gellert and the Szechenyi to tiny Ottoman Turkish-era hamams, some of them more than 500 years old.

All the drugery of dishwashing in this three-times -a day task, which comes to the house wife who does her own house work, has been eliminated by the new dish washer shown in the photograph on April 25, 1921. It is the invention of a Cincinnati school teacher, who sought to make things a bit more pleasant for his wife. Incedently, his idea was worth 12,00 to him, for a manufacturing concern thought so much of the “dish-washer” they purchased the rights and will seek to add a little joy to thousands of other housewives. With the aid of only hot water, dishes placed in a wire rack and set into the drum are made clean and spotless in two minutes. (Photo by Bettmann Archive/Getty Images)
