I looked down at my keyboard just now and noticed that the painted letter "N" has nearly completely worn away. All the other keys have their letters intact.
What is it about "N" that makes it wear out first? Do I use it more often? There are two "N"s in Kenerson, which I type quite frequently, so perhaps that's the problem. But there are two "L"s in "Bill", so why isn't the "L" worn out, as well?
Don't even get me started on "E".
