Teacher Denise, 55, gives a surfing lesson to Maria Ines (C), 69, and Regina Palomares (L), during their surf class in Santos, Sao Paulo state, Brazil March 16, 2016. When work is up, surf is up in Brazil, as a group of retired citizens take to the waves in keep-fit, keep-young sessions at a surf school in the city of Santos. The classes are run for free, three times a week at the Cisco Arana school, which aims to prove that age is just a number. (Photo by Nacho Doce/Reuters)
