Reordering Time

We generally tend to mark time by decades but I'm convinced we are grouping the years incorrectly. Instead of using years ending in zero, to mark a decade we should use years ending with a 5 as in:

1955 to 1965

1965 to 1975

1975 to 1985

1985 to 1995

1995 to 2005

I'm not sure why but it's easier to see things chronologically this way. Maybe it has to do with the election cycle. Still I doubt people are willing to give up those catchy nicknames like the Sixties and the Seventies.
