|1.||Half your age plus five|
Same as Half your age plus seven, but is the rule in Tasmania.
Alex wanted to date Meg but the 'Half your age plus seven rule stopped them'. However they both moved to Tasmania and because of 'Half your age plus five' rule they were fine.
|2.||Half your age plus seven rule.|
A mathematical equation used to find the youngest age a person can date without being considered a disgusting, cradle robbing freak. (A/2)-7=Y, where A is your age and Y is the youngest you should date.
Conversely the rule can be inverted to find the oldest age a person should date. 2(A-7)=O, where A is your age and O is the oldest you should date.
John is 26 and dating a 20 year old named Kate, (26/2)+7=20. Their relationship satisfies the half your age plus 7 rule.
Kate is 20 and dating a 26 year old named John. 2(20-7)=26. This relationships satisfies the inverse of the half your age plus seven rule.
Derived from the half-your-age-plus-seven rule. Used to define the oldest that a romantic interest can be before the relationship is considered indecent. This rule is considered more accurate than the your-age-plus-half-your-age-minus-seven rule, which in some cases conflicts with the half-your-age-plus-seven rule.
Jackie and Dan were mutually attracted, but Jackie waited until she turned 21 to make a move on the 28-year-old Dan, thereby making it acceptable under the your-age-minus-seven-times-two rule.
The lower limit on the age of a potential partner for a person over 14, by socially acceptable standards. Used as a rule of thumb.
The converse is twice (your age minus seven).
The following online calculator makes the math easy and also calculates how long until an UNacceptable relationship becomes acceptable:
Dave: Yeh man, I totally banged that Kath chick last night.
John: Are you a pedo?! She's 15!
Dave: Nah, she's 15 and a half, half-your-age-plus-seven, I'm 17, so half my age is 8.5 and plus seven is 15.5.
John: ...Doesn't change the fact that she's my sister...
The social rule defining the youngest age one may date without it being socially unacceptable (or illegal). To compute the oldest one could date without it being socially awkward, simply subtract seven from one's own age, and multiply by two.
To compute the acceptable age an otherwise inappropriately matched couple would have to be before they could date, find the difference in their age, multiply by two, and add seven to get the age the older partner would have to be.
And remember, always round up when computing the youngest age you can date, and round down for the oldest. You know, just to be on the safe side.
Andy is 23, Betty is 19. Andy wants to know if they should date, so he computes half-your-age-plus-seven (18.5). This is an acceptable relationship.
Christine is 25, Donald is 43. Christine thinks she might be too young for Donald, so she reverses the half-your-age-plus-seven rule (36). This is an unacceptable relationship.
Eustace is 94, Frank is 46. Eustace considers the fact that half-your-age-plus-seven (54) makes this an inappropriate relationship to engage in. She also considers that she will be 110 before her relationship with Frank will be socially acceptable. She then considers the fact that she will be dead by then. Eustace continues on with her relationship with Frank anyway.
A convenient rule to define the youngest that a romantic interest can be before the relationship is indecent. Widely referred to and used, the rule has merit for usefulness. The full version states: "if you halve your years then add seven, you'll have the youngest decent age for a partner; if you double your years then subtract seven, you'll have the oldest decent age for a partner".
However it's somewhat flawed thanks to the poor mathematical ability of its authors -- it gives a different result depending on whether it is worked out for a younger or older partner.
26-year-old Barbara waited patiently until Jack turned 20, fulfilling the half-your-age-plus-seven rule, before pursuing him romantically.
This is a very old rule of thumb: it is the calculation applied to a man's age that provides the age in a woman that he is most naturally attracted to physically. (Things change of course once you begin to actually TALK! :-o )
In recent years it has been misapplied to mean the lowest age that would be considered "decent" for him to date.
This new interpretation of the rule is actually quite bizarre when you consider the remarkable range of maturity among adults of both sexes at all ages.
That 50 year old think's he'll be able to romance that 32 year old. I'm not surprised he's attracted to her - she is the proverbial "half-your-age-plus-seven" - but let's see how far they really go together.
