well, for starters, In my country The Good Old USA, the weak and the frail (as you call them) are not looked down upon, but are actually respected as the champions of freedom.
The frail I was referring to being the warped and damaged minds of individuals who go out and execute a bunch of innocent people,or perhaps resort to the use of a firearm over a verbal disagreement, the weak being there inability to cause harm and death to the same number of individuals without the power of a firearm or some form of device.
The elderly who are at times referred to as weak and frail are respected in all country's I should think.
