Well, a national study of 4,000 adults claims to have identified "the top ten preoccupations" of what workers are most likely to have during business meetings.
The top ten meeting distractions are:
Sex - 57 per cent
Holidays - 31 per cent
TV viewing - 26 per cent
Social engagements - 23 per cent
Meals/ food shopping - 21 per cent
Household bills that need to be paid - 15 per cent
Office politics/gossip - 14 per cent
What colleagues are wearing from a fashion perspective - 10 per cent
Getting a promotion - 7 per cent
Eating chocolate - 5 per cent
There are more details about the survey to be found in the following article - When did you last imagine your boss naked? (Michael Millar, Personnel Today).
I tried to get a link to the actual report, but there just doesn't seem to be one. FYO the survey was conducted by Taylor Herring for Sky TV.
