Despite technological advances, scientists have not been able to extend man’s age on earth. The only way individuals can improve their quality of life is by embracing positive lifestyle activities such as eating healthy food, sleeping well and practising regular exercises.
Aging is an accumulation of chemical damage to the molecules inside our cells, which damages the cells themselves, and therefore the tissue, and then eventually us as an organism. Surprisingly, we start aging when we’re in the womb, although at that point, we’re growing faster than we’re accumulating damage. Aging happens throughout our lives, right from the very beginning.
Experts have likened the human body to a city containing lots of systems that must work together. Once an organ system critical to our survival fails, we die. For example, if our muscles become so frail that our heart stops beating, it can’t pump the blood containing the oxygen and nutrients our organs need and we die. When we say someone dies, we mean the death of them as an individual.
In fact, when we die, most of ourselves, such as our organs, are alive. This is why the organs of accident victims can be donated to transplant recipients.
