Most of us know exactly what we are talking about when we use the word ‘old’ and can easily determine the exact age of people, animals, and even plants when we use our intuition. However, there are certain situations where our intuition fails us; sometimes we aren’t even sure how old something is until we look it up in an encyclopedia or dictionary. In these situations it’s helpful to use a scientific method to determine the age of objects. Fortunately, the science of gerontology has changed all that and nowadays it’s much easier to determine the age of an organism than it has been in decades past. The reason for this change is simple – the average life expectancy has increased significantly over the decades which means that there are now more people in the world who are surviving into old age than ever before. This is great news for those who love animals and don’t want them to be killed off by diseases and parasites that ravage the species as we know it. It also means there is now a vast amount of data available regarding aging that scientists can study and learn from. With this data, it’s become possible to determine the exact age of any given organism with some pretty cool scientific methods that rely on math and biology rather than just intuition and common sense. Let’s take a look at how gerontology works and how you can use it to determine the age of Robert Pattinson (and any celebrity you might happen to love).
How Do You Measure Age?
The most basic and most important thing to note regarding the science of aging is that there is no exact measurement for it. Just as there is no exact measurement for height or weight, there is no exact measurement for age. The closest measurement you will ever come to is the saying ‘time flies’, but even this is not exactly what it means. Time flies for everyone, regardless of age, and it is not necessarily the case that the older you get, the faster it goes by. To give you an idea of how much time can vary from person to person, it is said that the average human loses seven years, about 10 months of life expectancy every year. This is why it’s so important to study the science of aging and learn how to determine someone’s true age. There are actually several ways in which you can do this; let’s take a look at some of the more common ones.
The Birthday Method
One method that researchers and scientists use to determine the age of an organism is called the birthday method. This method is rather straightforward and it relies on the fact that all living things age and eventually die. If we want to determine the age of a celebrity like Robert Pattinson, all we need to do is find the year of their birth and then add seven to it. Since most people know what year they were born in, this is a rather easy method to use. For example, if you know that Robert Pattinson was born in 1986, then you can figure out that he is 28 years old. Scientists use the birthday method to determine the age of organisms because it’s the easiest and most convenient method available, however, it is not necessarily the most accurate. There are other methods that are more precise, but the birthday method is usually good enough for our needs.
The Gerontology Lab
Another method that scientists use to determine the age of an organism is called the gerontology lab. The gerontology lab is a place where scientists study everything from the effects of aging to the aging process itself and the role that nutrition, behavior, and environment play in determining how fast someone ages. The name ‘gerontology’ comes from the fact that it is the study of aging and one of the most prominent (and most useful) studies performed in the field is the Minnesota Starvation Experiment. This experiment was performed in the 1930s and it involved feeding fruit flies (Drosophila melanogaster) different types of food (this food was designed to be nutrient-poor so that the scientists could study the effects that a lack of nutrients had on the aging process). A lot of the foods that the fruit flies were given had a high sugar content and a lot of animal protein, which causes us to question whether or not the age that the fruit flies were classed as ‘old’ as similar food would make us ‘older’ as well. It’s rather interesting to note that the scientists who performed this study did not feed the fruit flies any vegetable matter at all during the duration of the experiment because they wanted to see how malnutrition would effect the aging process.

The Chromosome Theory
A third method that scientists use to determine the age of an organism is called the chromosome theory. This theory states that our overall health and appearance decrease as we get older because our DNA is constantly changing as we age. In other words, our genetic material becomes less ‘efficient’ as we get older, which leads to us looking and feeling less like ourselves each year. The theory behind the chromosome method is that each year we add an extra strand of DNA to our genetic material and since the DNA is constantly changing, it makes us appear and behave differently as we age. While this theory has helped to improve our understanding of aging, it cannot be applied to everyone and it certainly fails to explain some of the quirks of aging. For example, it cannot tell us why some people age slowly and appear to have kept all of their youthful looks while others appear to have aged significantly overnight and don’t look like they have ever been a part of this world. Additionally, this theory also does not account for the fact that men almost always age faster than women and that people of the same ethnicity can vary significantly in the way they age. Nevertheless, the chromosome theory is a commonly used tool for scientists and researchers because it provides them with a framework for understanding aging and allows them to make better and more accurate predictions regarding an individual’s age. The chromosome theory can be used to determine the age of an organism by looking at their DNA and comparing it to a database of known DNA sequences.
The Calypso Method
The final method that we will discuss for calculating someone’s age is called the Calypso method and it was first described in a scientific paper published in 1986. The Calypso method is a little harder to use than the previous methods discussed but it provides us with a significant amount of information regarding an individual’s age. The Calypso method examines certain cells in the human body and assigns each cell a maturity rating based on nine different criteria. These criteria include things like the size of the nucleus, the amount of organelles (small bodies inside the cell that contribute to its function), and the amount of DNA contained in the cell. It then uses this information to calculate a score that represents the approximate age of the person. The Calypso method is rather more advanced than the previous methods discussed and it requires a trained eye to accurately calculate someone’s age. However, it is a great tool for scientists and researchers because it provides them with a lot of information regarding the age of an individual, which allows them to make more accurate and reliable predictions regarding that person’s health and longevity. Additionally, many people have individual variations in the way they age that this method can be used to determine the specific causes of these differences. The main drawback to this method is that it is rather time-consuming and it requires a significant amount of training to use it accurately. For example, it takes about six months of specialized schooling and four weeks of supervised practice to learn how to use the Calypso method efficiently and accurately. Luckily, the more time that goes by, the more accurate this method gets which makes it worth the time and effort. The Calypso method is a great option for scientists and researchers who want to study individual differences in the aging process because it provides them with a large amount of data regarding that person’s age, which allows them to do so.
