>Not having anything other than your job is bad
By "not having anything", I assume the OP is referring to things that give meaning.
>And no matter how much meaning and happiness you believe you are getting
This is awfully presumptuous and condescending.
>when your body and mind give out, that choice will be taken away from you and you will be taking time off from working, just not in a very pleasant way.
You mean when I'm not able to sustain long hours anymore? I'll have enough money saved to simply cut back on work. No spiraling health crisis necessary.
The quote you reply to says nothing about meaning and happiness, just health.
And no matter how much meaning and happiness you believe you are getting, when your body and mind give out, that choice will be taken away from you and you will be taking time off from working, just not in a very pleasant way.
