Hi,
I remember a surgeon that could rest his body and mind during a long surgery. He would lean against the wall and close his eyes for 5 min. Some people said he meditated while in this position. I do not know, really. Some people can do some stuff to cut through stressful time at the office. I used to get out of the office, get some tea and read a bit of a book I was reading and that did the trick. I never learn how to meditate but lying down
