What takes more energy, 2 meetings of four hours or four meeting of 30 minutes? The latter say American Psychologists. One week long they made test persons take notes of what they did and how they felt. Analysis showed a clear connection between the number of meetings end the fatigue / perceived work pressure. Interestingly enough, the content nor the length of the meetings seemed to matter. The investigators believe meetings break the daily routine and with an head full of work thoughts, employers need to take new information in at meetings. The more this happens the more we feel tired.

Comment: 
If this is true for meetings in workdays, how does this translate to sessions in conferences? Is it than correct to say that it is not good to have 36, 10-minute presentations like in many medical association meetings? Medical professionals go there to learn, but do they actually learn? Do they rightly get CME’s (points for Continued Medical Education) for attending? And do presenters rightly earn even more CME’s for giving such extreme short presentations?Should we not than have 3 times a 2,5 hour presentations per day as a conference standard for good learning?
