- It gets even more astonishing: each cell is a world unto itself, jammed full of nanomachines and millions of moving parts. In an extraordinary feat of coordination, each cell is also connected to the rest of the body, fine-tuned to perform its own functions and yet respond to the body's overall needs.
May 21, 2021 · It's jarring to see four questions grouped together, about why we're prone to choking; why infertility is widespread; why so many people need braces; and why females menstruate.

Fig 1: Chromosomes (grey) shown with their telomeres (white dots) at the end. Telomere shortening is one well-known factor that leads to our cells losing the ability to divide. Our DNA is stored as tightly wrapped strands which form structures called chromosomes. Telomeres are located at the very end of chromosomes, seen as bright dots in the image...
We are constantly under attack from our environment, and our bodies accumulate damage over time. Damage affects the DNA, proteins and fats in our body which break down and weaken various components that we need to survive. Fig 2: Bill McElligott showing uneven sun damamge from driving for long hours. One symptom very commonly associated with aging ...
This question becomes more complex when we compare how other species age. We see that not all species follow the same tendencies as us. On the graphs below, we see our fertility and mortality (or likelihood of dying) displayed over our lifetime. As expected, we see a peak in fertility in our early years, and as we get older see a sharp increase in ...
Jun 18, 2024 · Our bodies are not only fearfully and wonderfully complex but vitally en-storied. Understanding our past (as human), our future (in Christ), and our present (in the Spirit) is critical for duly appreciating, chastening, and making the most of our bodies in this life. So let’s rehearse the story. 1. Sin has seized our bodies.
Mar 23, 2021 · Programmed aging theories say that people are designed to age and that our cells have a predetermined lifespan that’s encoded into our bodies. Also called active, or adaptive, aging theories...
Dec 22, 2019 · According to evolutionary biologists and psychologists, many physical and mental ailments result from a lack of fit between the environment people evolved for and the one in which they now live —...

What happens to our body as we age?
The cells in our bodies live for anything from a few hours, in the case of certain types of white blood cells, to a few weeks, for skin cells, to many decades, in the case of most brain cells. But while most cells are regenerated, the processes involved become progressively unreliable over time.
