The greeks have an obligatory military service lasting one year. The army choose every year
the biggest and strongest men among the young people doing the service, and propose them to enter
in the presidential guard. This means a hard training, that starts with a violent harassment,
according to rumors. The presidential guards are called "the evzones" ("beautiful belt" in greek).
Some stay in front of the parliament, and the changing of the guard happens every hour.
This is the occasion to see an amazing choreography. The evzones protect the presidential residence,
keep an eye on the grave of the unknown soldier, and pose for the pictures with tourists.
