IN A NUTSHELL
How do our bodies grow?
Our bodies grow because of built-in instructions we’re born with. These natural “growth forces” come from our heredity — the genetic plan that guides our development from the very start.
We move through several stages of growth: embryo and foetus, infant, child, teenager, adult, and finally old age. Growth is incredibly fast in the first weeks and months of life. By the end of the first year, the pace already slows down. Throughout childhood, we grow at a steady, moderate rate, until puberty arrives. Then the body speeds up again, bringing on those noticeable teenage growth spurts.
Even though human beings follow the same general pattern, everyone grows in their own unique way.
Boys and girls share the same stages, but each person develops at slightly different times and speeds.
Growing Fact:
At birth, the bones in a baby's head are not fully fused. The bones are still separate, making the head flexible enough to move through the birth canal. These bones gradually fuse, but the soft spot on top — called the fontanelle — take several months to fully close.
How do we age?
Aging happens because the body slowly becomes less able to repair and replace its cells. Each cell can only divide a certain number of times. As they approach this limit, cell division slows down, and sometimes the new cells aren’t as effective as the old ones. When this happens, organs don’t work as well, tissues start to change, and the chemical reactions that keep us going become less efficient.
The brain is especially sensitive to aging. As brain cells receive less oxygen and fewer nutrients, forgetfulness becomes more common. Interestingly, older people may forget recent events but remember childhood moments very clearly — those early memories can bring a lot of comfort and joy.
Ageing Fact:
As people age, their skin becomes looser and forms wrinkles. This happens because collagen — the protein that keeps skin firm and supportive — becomes weaker over time, letting the skin sag into creases.
