my family belived in 生老病死 But I believed in 生死. To me everyone will went through both 生死 rather than the whole process of 生老病死. Not everyone have the chance to be born and lived on so there's only 生死 Not 生老病死. And some even sleep to death without any proper logical reason. Yet again 生死 Not 生老病死. Hence, I believed in 生来死 Rather than 生老病死.
