Xkcd formula for dating
A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years.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. But as you get older, the dateable age range gets wider. The first chart is labeled Singles, and is a decreasing graph.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).The upper limit can be defined as y = 2(x − 7) in which x is your age and y is the maximum age of your partner.As age increases, the age range of potential non-creepy partners widens. The same also works with infinity, but even Methuselah died once.
The intuitive conclusion is that the number of potential partners is decreasing as time goes on.
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...
