Expressões com a palavra nothing #4: think nothing of

I have a cousin who's very athletic. He sometimes gets on his bike and goes straight to the beach that is like a lot of miles away from his home. And I think he would think nothing of running a marathon before breakfast.

When you think nothing of doing something that other people find very difficult, you do it very easily. When my brother was young, he thought nothing of joining the Army and living a life that is totally different from what he lived up to that point. When my family came to live in the capital, my mother thought nothing of having to wake up before 5 a.m. and go to work in her old city. Many people would find that routine too overwhelming, but she seems to be doing very well. Okay, that's all for today.
