eli5: If the bottom of the ocean is super cold and the inner core of the earth is super hot, where in the earth’s core is it “just right”?

Question

Barring the immense pressure and lack of oxygen, I’d like a nice 75 degrees or so

Answer 1

You don’t need to go very deep underground for it to start getting relatively toasty, only a mile or two, depending on where you are in the world.

[In the deepest goldmine in the world](https://en.m.wikipedia.org/wiki/Mponeng_Gold_Mine) the rock gets up to 66C/150F once you get to the deepest point some 4 kilometres down. Since it’s a working mine, you can obviously even get oxygen there. 

The pressure isn’t a problem until it is, I know from first hand experience that the rock closes in fast on any tunnel you drill on it. As in, you can literally measure it with a tape measure and a watch.
