the science of getting old: 5 why’s you’re growing older and what to do about it – daily infographic
You already know that getting older is inevitable. But did you also know that your body is telling you when it’s time to prepare for the inevitable? In addition to the physical changes your body goes through as you age, there are several biological reasons why our bodies begin to wear out over time. The good news is that when we understand these reasons, we can make lifestyle choices today to help us live longer and healthier lives in the future!
The first step in understanding how aging works is to understand what’s going on in your body right now. Your cells are made up of molecules and atoms, which are constantly moving around. What we call “aging” is really just the process where our cells stop dividing and start dying off. This happens because the DNA inside each cell can only be copied a finite number of times before it starts to become unstable, causing genetic mutations that can lead to cancer or other diseases like Alzheimer’s disease. Fortunately for us humans (and most other mammals), our bodies have evolved mechanisms that allow us to replace old cells with new ones so that we stay healthy throughout our lives—even as those cells continue dividing at an accelerated rate compared with younger people.
The first question to ask is why your hair is turning gray. The answer lies in the follicle cells that produce pigments—the melanocytes. These cells are responsible for producing melanin, the pigment that gives your skin and hair its color. As you age, these cells stop producing melanin and thus cause your hair to turn gray. The second question is why do those melanocytes stop working? There’s no definitive answer here; however, research has shown that aging may be one factor contributing to this process (although we don’t know if it’s the only factor).
Skin wrinkles because it loses elasticity. The loss of elasticity is due to a decrease in collagen, a protein that makes up the connective tissue of the body. Collagen is broken down by enzymes called matrix metalloproteinases (MMPs). However, this isn’t the only reason why you’re growing older and wrinkling—there are other factors involved as well!
There are five main reasons why we forget things; Our brain is not as strong as it used to be, We’re not using it as much, We’re not exercising our brain by learning new things and trying to remember them, The older you get, the more your memory declines due to a lack of stimulation from new information or activities and As we age, so does our ability to learn new skills and retain memories for longer periods of time.
We lose height as we age. The discs in your spine lose fluid, which makes them shrink. This causes the vertebrae to become compressed and shorter. The compressed vertebrae are more likely to rub against nerves and cause pain.
One of the most noticeable changes that occurs with aging is a decrease in visual acuity. You may notice this when you’re trying to read tiny print or when you’re trying to see something up close. It can be frustrating, but there are some things you can do about it. The problem is not just in your eyes, though—it’s also in your brain. As we get older, our lenses don’t change shape as much as they do when we are younger and so our ability to refocus does not work as well. We also have more difficulty seeing differences among shades of color or contrasts between light and dark areas (such as shadows), which makes it harder for us to see contrast sharply enough for detail recognition tasks like reading small text on a page or writing checks at night time without turning on additional lights in our homes! Aging affects everything from how well we see things up close through how well we see objects far away such as signs along streets outside our homes.”
Aging is just a natural part of life and if we understand what to expect, we can better prepare for it We have to remember that aging is a natural part of life that we can’t avoid. By understanding the different stages of aging, we can better prepare for them and live our lives more peacefully.
