no me pasa nada
dar un portazo
saber a ciencia cierta
ponerse en forma
encontrarse bien (o mal)
dar pereza (a alguien)
más de la cuenta
de hecho
sin pegar ojo
too much
to get in shape (to get fit)
there's nothing wrong with me
to feel well (or bad, ill)
in fact
to slam the door
without sleeping a wink
to know for sure
to make someone feel lazy (literally: to give laziness)
