Mariana Fonseca, a Brazilian medical student, talks about her Rio.

In a special series to mark the start of the Rio Olympics, four Brazilians sent 'postcards' from their city to Radio 4's PM.

Mariana said there was a sense of excitement in the city but the problems will come after the Olympic Games were over. She wished the games were not happening this year.
