It is abnormal and unhealthy to ‘constantly’ think about death.
Mout Ka Ek Din Moayyan Hai
Neend Kiyon Raat Bhar Nahin Aati?
I think if you tell yourself death is inevitable and inescapable but does not have certain time that you can ever find out,… and engage yourself in daily activities like no tomorrow in positive way, then it will serve benefit not only to yourself but anyone around you.
