For convenience, the line representing x=y is also shown (in blue).The area between the blue and red lines shows where you are the older partner in the half-age-plus-seven calculation, while the area between the black and blue lines shows where you are the younger partner.Graph of the Half-age-plus-seven rule ("never date anyone under half your age plus 7"), which claims to dictate what age disparity between two people is acceptable in dating/romantic/intimate relationships during the late 20th century / early 21st century (called the "Standard creepiness rule" in the xkcd webcomic).According to this rule, the age of the younger person should not be less than half the age of the older person plus seven years, so that (for example) no one older than 65 should be in a relationship with anyone younger than 39 and a half, no one older than 22 should be in a relationship with anyone younger than 18, and no one under 14 years of age should be in a relationship at all...As radioactive Parent atoms decay to stable daughter atoms (as uranium decays to lead) each disintegration results in one more atom of the daughter than was initially present and one less atom of the parent.

According to this rule, it would not be creepy for a 30 year old to date a 22 year-old, but an 18 year-old would be off-limits.From a sexual attraction standpoint, I challenge you to stand me shirtless next to Sophia Loren in Look, Steely Dan probably couldn’t talk at all to "Hey Nineteen" because they admittedly had "nothing in common." Not because she was too young to name an Aretha Franklin song (which, like, come ON, Steely Dan); the idea that people are what pop culture references they know reduces falling in love to trading trivia. A lot of women have told me they won’t date younger men because of maturity issues, and that’s probably where the idea of a prohibitive "age gap" comes into play for a lot of people.As anybody who’s ever had to play "What are your top five favorite movies? A fantastic woman several years my senior recently told me I should only date older men, because even though I’m 28, "being in your twenties is a form of functional retardation." I think there’s a grain of truth there, if only because I don’t know anybody who looks back and thinks, "Man, how awesome was I in my twenties?All rocks and minerals contain long-lived radioactive elements that were incorporated into Earth when the Solar System formed.These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur. Its crust is continually being created, modified, and destroyed.As a result, rocks that record its earliest history have not been found and probably no longer exist.
