Up until now I always have been able to work all day without taking breaks (besides a mid-day lunch break) but I'm starting to feel the need to take a small break from time to time.
The problem is, I don't know what to do to make a break useful and efficient. If I do I often just do something else on the computer (checking my personal mails, social media, news...) and it does not feel like a real break at all.
What are your thoughts on this ? Do you take breaks at work ? If so, what do you do ? And for how long ?
