| WHY DON'T WE LIVE FOREVER? |
|
Have you ever wondered if we can live for eternity?
We live and die. Between the two, we age. Aging is the gradual decline of in
the body structure and function. Eventually, the body’s inability to ward
off diseases result in death. In fact, human are programmed to die! Cells reproduce
by dividing , and each type of cell undergo doublings. The amount of doubling
decreases as you grow. And research has shown that even cells taken from old
are transplanted to a young of the same species, the older cells still die at
the predestinated time. As the body age, there is an increase in the ‘wear
and tear’ pigment, and we show the outward signs of aging - our skin wrinkles
and becomes less elastic, our hair grays and thins, the body is less resistant
to infection, the sense organ become less sensitive. Worse, even brain cells,
which does not reproduce, will lose function with age. In the scientific aspect,
we age and die. However, we also grow wiser with age and become more experienced.
It’s never too old to laugh, or make new friends and to enjoy the fruits
of success during youth.
