If you work with computers or more generally, have to input information into some electronics device in your daily routine (keyboards, PDAs, mobiles, etc) there is a short tip that can give you the edge.

Having experienced data entry it was instructive to find that the speed and error rate of data entry are empirically proportional to the length of finger nails.

What?

Longer nails slow you down and increase the number of errors. By ‘long nails’ I mean 2mm or more. When you factor in the time spent correcting said errors, it amounts to more than the time it takes to cut fingernails. Even growth of 1mm has been found to make a significant difference. I now cut my nails regularly each week. (Cut as opposed to chew, which can leave fingernails ragged.  Ewww!)

So a shorcut to increased productivity is just that, “a short cut”.
