The common time period where the desirable, or sometimes undesirable, urge to change comes about. The need for dramatic change in life develops every 5-7 years.

This change grows within the human mind, both consciously and subconsciously, and implements necessary action "To Do" something different even though, many times, there is really no need in your current life to do it (ie, Happily Married, A Steady Job, Steady Income, Nice House, etc).

The human mind continually seeks and desires change every 5-7 years in life, for without it, the mind would have nothing to do and no where to grow.
"7 Year Itch"

47-53: Settling down, preparing for retirement, traveling, grandchildren, realization of how short life is for everyone.
54-60: Retirement, if you're lucky, slowing down and settling down, continually dealing with less and less of others who you were close to in life actually being around.
61-67: Living life to the fullest and trying to be happy and thankful everyday that you wake up. But for many, just counting the days to death.
68-74: Have your life insurance plan set and ready for your family, pick your coffin, burial site and more. Pray.

Get the 7 Year Itch mug.
The "7 Year Itch" comes from a 50's movie. There is a natural tendency to get bored with your romantic / sexual partner after awhile (7 years).
That dude's got the 7 year itch, he's screwing everyone but his wife.
