I was a soldier and serve my country for 20years, I spent 12years going to war and I became a General for 6years, my grandpa told me; all the things running through my mind is that "what happen to him, because he looks weak and sick". Then I replied him, can I ask you a question, you can said grandpa. You look weak and somehow sick everything I heard about you seems not to be so because I was told you are a very strong soldier and a hero of the country, you are suppose to be strong and healthy. Allow me to explain things you don't know said grandpa.
There is something we call 'FRAILTY',Frailty is a condition that involves poor health outcomes, increased vulnerability and comorbidity, and is also the the condition of being weak and delicate. As you know the older you get, the weaker you become even in the presence of good health. No one can be the same (from adult to old age).
A young individual can jump from a high building to the ground level without feeling a thing or fall and sustain wound from the fall, him that young boy few days, his back on his feet, but that equation is not apply to old ones because ones you fall from a high level ground you may likely die, because the body is weak. Young people can recover from sickness faster because there immune system is still active compare to old people.
You may wanna ask the causes of Frailty;
(1) Age: like I said, as you age, your body function changes.
(2) Disease: Adults with other health conditions, such as high blood pressure, diabetes, may be more likely to become frail or become frail faster.
(3) chronic conditions.
And the symptoms of frail are;
-fatigue
