Should you write code all the time, even in your free time?

I hear senior developers saying I shouldn't do it because I will get burned out, I hear not so experienced ones saying we should use every moment we have to write another line of code. Some even look down on you and think you're not passionate/ serious enough about your job, just because you don't breath code 24/7.

While I do do work related things after clocking out (and I'm not opposed to that, since I don't have a great deal of experience and there are many things to learn), I can't help thinking about that people working in other fields are not really expected to take their work home with them - I don't see my nurse friend going around and giving shots to her neighbors, after her working hours are done.

What's you opinion on this? Is the amount of time spent coding outside office hours an indicator of how good/ passionate of a developer you are?
