People who've reached 110 can pretty much do whatever the fuck they want, provided they aren't breaking any laws outside of drug ones. As in, determining if the older party is acting in a potentially predatory manor based on the naivety of the younger.
If someone 110 wants to continue doing coke every day, I'm not going to stop it. So the fact that the range gets pretty large starting somewhere around is based on people past their mid-30s having enough life under their belt to make good decisions for themselves.
The Half Plus Seven Rule is an unwritten rule which asserts that it is creepy to date anyone who is younger than half your age plus 7 years.
For example, a 50 year old dating someone who is 31 or younger would be classed as creepy.
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.
The problem is that both the equation "y = x", which just maps age over time, and "y = x / 2 7", the dating-range formula, are each linear, an so at a certain point the lines grow unrealistically far apart, like where a 60 year old can date a 37 year old.
When thinking about it, I figured what you'd want is some kind of curve that had an asymptote parallel to y = x, that way ages wouldn't become unrealistically far apart. What's wrong with a 60 year old dating a 37 year old?
(And people only slightly older than 14 should only be involved with those almost exactly the same age as themselves.) To read the chart, go to the position along the x-axis which corresponds to your age, and the green range (between the black and red lines) directly above that position corresponds to the range of your partner's ages which is deemed acceptable by the rule.
Downloading the excel file at A1-all.xls, we can continue the analysis and replicate Randall's findings.
I edited the data found in the csv file to compute the age pools of singles by considering that the "single person" category is the union of the categories "Married Spouse Absent", "Widowed", "Divorced", "Separated" and "Never Married".
While the application of this rule actually reduces the number of potential matches further, Cueball presents it in a positive way.
By showing that there are whole swathes of people who she couldn't marry in the first place without being in a creepy relationship, and that as her age increases the range of non-creepy partners increases, combined with Census Bureau data, Cueball shows that her eligible dating pool is in fact still increasing.
