Either you know how the life expectancy is calculated and how the WHO itself has studied the most sensitive parameters open to manipulation in a number of papers....or you dont. If you want to ignore the challenge and thats your best argument, well so be it.....BD is a well of ignorance in more ways than one it seems then.
Now if you have some international NGOs reports on any health and sanitation matter regarding poor insitutional capacity BD...detailing their sampling strategy and methodology, lets see it. I have asked many times before, not one of you could provide it...just that "BRAC" is "credible"....well lets see the details.
Till then Bangladesh is a terribly corrupt country I wouldn't trust anything automatically...everyone has to be like the UN now? The same UN that puts massive human rights violators (countries that stone and behead people on flimsy evidence and judicial procedure) on organisations that deal with the very same subject?...just because they are members and thus equally credible to any other member? The same UN that takes North Korea, Cuba and other completely closed, authoritarian countries health propoga...err data verbatim too? Yeah pass.
If BD is so super duper on sanitation, the economist wouldn't have noticed the nasty stench, open effluent and god knows what else (probably have to leave the safer areas which they probably didn't) in Dhaka in their liveability index (and made Dhaka take a terrible hit on the relevant components)...ranking Dhaka next to complete warzones in libya and syria. Thats the kind of thing that happens when you send direct observers instead of harnessing BBS claims directly....and even in that index they took some BBS claims (because who wants to spend tons of time gathering every specific in Dhaka especially), so who knows how much worse it would be if they trusted absolutely nothing (and if they cared enough to do so).
Thats the thing with BD, no one really cares about it in the first place. There is a happy well of self-imposed denial and ignorance respectively on either side. Only a few truthful people like
@Mohammed Khaled and my RL friends from BD matter in the end....in challenging this BBS hoax.
Is it any surprise? Look at where the BD govt is ranked in corruption, and worse yet not improving an inch:

It gets even worse if you read the full report in specifically what BD govt is stagnating in.
