It's not wrong thought thou! Brazillians are like that most of the time. You see them disappear when they hit 30 of age! and Most of them are unprofessional, homesick, huge bellies

and hard to discipline etc..
But in the end, there are always exception. Just like Africans are sporty and hard workers in general, it's not wrong to say the same for Brazilians (in general again), unless you want to play the "intellect"
