they are older than me

I have two brothers, and they are older than me.
Tengo dos hermanos y son mayores que yo.
Those two think they can tell me what to do because they are older than me.
Esos dos creen que me pueden mandar porque son más viejos que yo.
They are older than me, so they have a lot of experience that I don't have.
Son más grandes que yo, así que tienen mucha experiencia que yo no tengo.
