"a majority of researchers and scientists had conflicts between their work schedules and personal lives at least two to three times a week."
"about 60 percent of scientists were happy with their work-life balance. The rates for women were lower, at 52 percent."
I wonder what differentiates these 60 percent 'happy people' from the remaining 40 percent. What do you think are good strategies for a healthy work-life balance? How do you balance your academic work/life with your personal life?
In my experience, there's less distinction between work life and personal life than in other jobs. If you're teaching, you'll get emails from students on the weekend and late at night. A paper deadline at midnight doesn't care that you're supposed to finish at 5. If you're working on an interesting problem, you're going to think about it at home.
I think the way to be happy with that is to simply accept it. If you're counting on having a 9-5 job if you're paid for working 9-5, then you're not going to be happy in academia. If you're uncomfortable with the line between work and personal life being blurred, you should perhaps consider a different job.
