It's not simply whether you make time or not for everyone. I'm not talking about myself, but I'm just saying that I do know people for whom they wouldn't have time to go to the gym, get dressed, work out for an hour, shower, then go home and such. I'm a law student, so I'm thinking of people I know who have kids and such, but there are also, e.g., med school interns, sometimes architecture students, etc, who--I'd venture to say--literally wouldn't have the time to do any sort of regular routine.
That said, it is whether they "make time or not" in the sense that they made the choices that got them there. No offense, but majoring in physics doesn't mean much to me. It's not difficult subjects that are worrisome; instead, it's the major/course of study itself having a large facetime component that becomes problematic for some.
