How long do bearings last?

I bought these red bone bearings for my longboard and if i go down hill like little fast and just like carv and go side to side, will that ruin my bearings or what will thank u

Personally my friend has a longboard with bone reds and he carves, powerslides, and just about everything else, and his bearings are still good today. (He got them installed 2 years ago). And he rides pretty much everyday.
