If you have ever heard the expression "Publish or Perish", trust me, it is true. Being in academia is all about stressing over grant applications or stressing over publishing or stressing over research or stressing over teaching or stressing about how much coffee you have left in your desk drawer and whether it is enough to get through the day. Actually, the last one is my personal addition ;) I have children on top of being an academic so coffee is very important ;) Please don't get me wrong.... I still love my job but I can totally understand why most senior academics have a lot of grey/white hair ;)
Wishing you all a happy day!
