What that article doesn't comment, but I hope that it implies it, is the fact that during the time we consider as working hours should be dedicated for that purpose.
So in titles the 10 way's history's finest kept focused at work
1. Don’t work long hours (tell that to my supervisor)
2. Take breaks
3. Take even longer breaks (that one is my favorite)
4. Stop work and sit down for meals (I'm already into this one)
5. Don’t work in the afternoons (actually I'm trying not to work even in the morning)
6. Mix it up (done that)
7. Aim low (all I need is a roof above my head, a plate of food to eat, and a woman to love)
8. Take time to relax (isn't that one consistent with points 2,3,4,5?)
9. Get up early(?) (I couldn't argue more with question mark, but waking up early has some advantages, I can recall none of them right now, feel free to add some)
10. Exercise! (no comments)
