Lines I had to write at school still apply after 50 years have got behind me.
I must concentrate on the job in hand!
Can also be seen in those (like me) who find solving other peoples problems easier and more enjoyable than solving your own. Sometimes this is because you enjoy the company! I still think it is because you can walk away from other peoples problems, but you are usually stuck solving your own problems by yourself. Hope that is not to deep or non understandable for this thread.
