Nearly a quarter of business travelers say they have nodded off in a meeting because air travel deprived them of sleep.(British Airways/Darryl Haralson and Jerry Mosemak, USA TODAY)

One of the other stats says that 18% of business travelers said that sleep deprivation caused them to give a poor presentation (I wonder if that means 82% of business travelers have never given a bad presentation). How do you figure something like that out? The sad thing is this is something that is likely to be forwarded around offices worldwide under the guise of being meaningful.
