I don't know if this is a valid reason or not. But ask people who have to take medications every now & then. There are times when they think like oh what the heck why do we have to be dependent on "dawaiyaan" unlike others around us.
Its just that feeling that you don't wanna be always dependent on that stupid medicine in order to be able to do daily chores & then you see people around you who are MashaAllah all healthy.
On top of that our Desi culture that oooohhhhs & aahhhhhs on "becharay bemar" people.
I hate it when some Desi aunty finds out about a person who has some sort of terminal illness & with her "hai hai" makes it sound even more miserable.
