:) I am glad you had some time off :D Even the best job could exhaust you if you are not careful enough. 

> Although I am not self-employed, the work I do is really interesting and I could say I enjoy like 80% of it.

I know what you mean. I was engaged in a very interesting project for the past two years. I really enjoyed it and I didn't mind working on weekends or late nights. We were assessing candidates for a very specific job position and it was like a game - putting the pieces of one's character together, making predictions for their future behavior. I felt so curious and intrigued all the time. I never got bored. I suppose your work is similar :) It seems to be very interesting! I know you have posted some articles about the lie detector before, but I haven't had the chance to read them, yet :) 

Thank you for your kind comment! See you!
