are missing out
Estás perdiendo una oportunidad increíble al no participar.
You're missing out on an incredible opportunity by not participating.
Estás perdiendo demasiado tiempo.
You're wasting too much time.
¿Estás estudiando para el examen o estás perdiendo el tiempo?
Are you studying for the exam or are you wasting your time?
No sabes lo que te estás perdiendo.
You don't know what you're missing.
You're losing blood.
You're losing me.
Estás perdiendo contacto con la realidad.
You're losing touch with reality.
