Modesty aside, at age 81 I think I have stronger immunity against COVID-19 than many people I know in their fifties or sixties who have been smoking or drinking heavily, sleeping only six hours a day on the average and indulging in unhealthy diets.  I have good genes (my mother lived up to 102 years of age).  I have tried to live a healthy life style at least for the last twenty years of my life.  That is why I felt aggrieved when under the General Community Quarantine (GCQ), I could not move as freely as those below 60 years of age.  I really think there has been no scientific foundation for the classification of people by age for purposes of the various stages of quarantine under the global pandemic.  I was glad to learn that the World Health Organisation (WHO) had declared that 65 years of age is still considered young .  According to new research done, human age is now divided as follows: 0 to 17 years of age: underage; 18 to 65 years of age:  youth/young individuals; 66 to 79: middle aged; 80 to 99 years old: elderly/senior; and 100+ years of age: long-lived senior.
