Ever heard of the rule that men should date women who are half their age plus seven? Some celebrities – think Leonardo Di Caprio – take this to extremes with a roster of something models regularly appearing on their arm, but do you know where the saying comes from? But does it stand up to scrutiny, or is it just a baseless rule perpetuated by men who want to justify dating younger, and less mature, women? We asked three relationship experts to weigh in on the rule – and their responses were surprising. Historically, a woman was to choose a man the same age, or five to 15 years older. Mid-century, the reason for the elevated age gap would’ve been economic. Women had little ability to earn income. Their husband was their access to social standing and economic stability.
Substantively, this dating age formula states that you should not date someone younger than half your age plus seven. Properly used, the formula provides an age band within which are ages that your partners should be. As pleasant as this rule is, it is mostly theoretical and demands a more applicable version. This post provides that more applicable version. This presents two specific problems.

When you measure your baby’s development—that is, when you look at what is “normal” for your baby’s age—consider both of those dates. Begin with your baby’s actual age in weeks number of weeks since the date of birth and then subtract the number of weeks your baby was preterm. This is your baby’s corrected age. A pregnancy is now considered “full term” at 39 weeks.
To determine the number of weeks’ preterm your baby was at birth, subtract gestational age at birth from If your baby was born at 32 weeks’ gestation, she was 8 weeks 2 months preterm. If she is now 4 months old 16 weeks since birth , her corrected age is 2 months.

What about overlaying the line also on the “oldest preferred” data? That is, do men’s preferences also closely match the “rule” dating they’re the younger ones?

Early or Late Retirement?
We are seeing large age gaps in the dating pool and not just the typical old-man-younger-woman narrative. For example, a AARP study reported that 34 percent of women over 39 years old were dating younger men. Add in the popularization of divorce over the last 50 years and the introduction of dating apps, and matters of love, sex and how we connect are utterly transformed. Love is a melting pot. I find it refreshing that society has begun to validate the simple fact that relationships no matter how short or long can still be meaningful.

Relationship advice Does age matter in a relationship? So given all this, do traditional notions of appropriate age gaps in relationships still matter?
What is traditionally appropriate? What is traditionally deemed acceptable changes with age, especially as people grow older. According to some, you can determine your appropriate dating age range by only dating someone who is within a fifth of your own age. Family planning If having a family is something you want from a relationship then obviously age differences become a bigger consideration.
Financial, health and economic factors also change as we grow older and these can sometimes make child rearing more difficult in later life. 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.

In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon is a key element in biologically important molecules. During the lifetime of an organism, carbon is brought into the cell from the environment in the form of either carbon dioxide or carbon-based food molecules such as glucose; then used to build biologically important molecules such as sugars, proteins, fats, and nucleic acids.
These molecules are subsequently incorporated into the cells and tissues that make up living things.
The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years. For example, a.
Megan is upset because she is apparently older than 26, and among people who marry, half do so below The intuitive conclusion is that the number of potential partners is decreasing as time goes on. The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years.
As the graph shows, there is a lower limit and an upper limit. As age increases, the age range of potential non-creepy partners widens. At 26, the range of non-creepy partners is 18 years to year-olds. At 50, it is 54 years 32 to 86 years old. At age 14, you can only date people your own age. The same also works with infinity, but even Methuselah died once. While the application of this rule actually reduces the number of potential matches further, Cueball presents it in a positive way.
What Age Is Appropriate for Dating?
Age disparity in sexual relationships is the difference in ages of individuals in sexual relationships. Concepts of these relationships, including what defines an age disparity, have developed over time and vary among societies. Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross-culturally. There are also social theories for age differences in relationships as well as suggested reasons for ‘alternative’ age-hypogamous relationships.
Age-disparity relationships have been documented for most of recorded history and have been regarded with a wide range of attitudes dependent on sociocultural norms and legal systems.

Although this is a fun rule of thumb, what does research say about age preferences for potential mates? From an evolutionary perspective , it makes sense for women to prefer mates with resources and to like partners who are more established, both of which are more likely in older partners.
Men, in contrast, are hypothesized to be most attracted to women in their reproductive prime, which tends to be when they are younger. Data from Kenrick and Keefe 1 support these predictions.

Workers planning for their retirement should be aware that retirement benefits depend on age at retirement. A worker can choose to retire as early as age 62, but doing so may result in a reduction of as much as 30 percent. Starting to receive benefits after normal retirement age may result in larger benefits. With delayed retirement credits , a person can receive his or her largest benefit by retiring at age For example, if the number of reduction months is 60 the maximum number for retirement at 62 when normal retirement age is 67 , then the benefit is reduced by 30 percent.
Delayed retirement credit is generally given for retirement after the normal retirement age. To receive full credit, you must be insured at your normal retirement age. No credit is given after age
BMI Percentile Calculator for Child and Teen
Age-based formulae have been widely used to predict the appropriate size of the endotracheal tube ETT in children. These formulae are based on old data from Western countries. The current study was undertaken to assess the effectiveness of these formulae in Japanese children. We reviewed data for the past 5 years from children 0—8 years of age intubated orally with the regular uncuffed ETT or RAE type. Data from children were reviewed.

Bloggers and busybodies are divided over whether or not the age difference between actress Jennifer Lawrence, 24, and musician Chris Martin, 37, automatically renders their relationship inappropriate. The rule is widely cited, but its origins are hard to pin down. The rule also appears in The Autobiography of Malcolm X. When Malcolm X met his future wife Betty Sanders, he interpreted the fact that their ages fit the rule of seven as a sign that they were destined for each other.
Now, the half-your-age plus seven rule has entered the cultural lexicon. But the rule of seven may not actually describe what people consider acceptable. In , a team of Dutch social psychologists, led by Bram P. Buunk of the University of Groningen, examined desired minimum and maximum ranges across different ages by approaching people in public spaces—railway stations, libraries, malls—and asking them anonymously what ages they would consider appropriate for five different levels of relationship: marriage, serious relationship, falling in love, casual sex, and sexual fantasies.
They restricted their survey to people who fell within a year of five age groups: 20, 30, 40, 50, and 60, and asked a similar number of men 70 and women You are using an outdated browser. Please upgrade your browser and improve your visit to our site.

Because of possible rounding errors in age, weight, and height, the results from this calculator may differ slightly from BMI-for-age percentiles calculated by other programs. Birth Date must be at least 2 years before Date of Measurement. If the child is under 2 years old, BMI cannot be calculated.
Many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already exists. These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements. In this case, it is a big advantage to present the data in a form in which the abundance of both the parent and daughter isotopes are given with respect to the abundance of the initial background daughter.
The incremental additions of the daughter type can then be viewed in proportion to the abundance of parent atoms. In mathematical terms this is achieved as follows. When some daughter atoms are initially present designated D 0 , the total number D is the sum of radiogenic and initial atoms, so that. To establish the condition that both parent and daughter abundances should be relative to the initial background, a stable isotope S of the daughter element can be chosen and divided into all portions of this equation; thus,.
This term is called the initial ratio. The slope is proportional to the geologic age of the system. In practice, the isochron approach has many inherent advantages. With time, each would then develop additional daughter abundances in proportion to the amount of parent present. If a number of samples are analyzed and the results are shown to define a straight line within error, then a precise age is defined because this is only possible if each is a closed system and each has the same initial ratio and age.
The uncertainty in determining the slope is reduced because it is defined by many points.
