Well, I meant the typical 20-22 working days in a month (when you rest for 2 days in a week). 22 hours/day is kind of slavery.

Oh, sure, if they do care only about the height, it's sort of unacceptable
but what I meant is the
complex of their expectations, understandings, views. Let's say "they" (or "he"/"she") thinks that you should have own house, good job or own business and being in good shape (if not very fit, at least not an obese guy). And then, it's good to pay some attention to these good expectations and to try your best (better than being the opposite -- a homeless, unemployed and with ruined body, right?)
When their/his/her expectations are also good for you, you should give it your best try. But not if they're some evil people, for example, who'll make you to try bad things like becoming a gangster, joining aggressive armies, being a scammer and so on.
