Actually you are not smart enough to foresee that someone might actually have found conflicting information from an alternate credible source.
Demographics of India - Wikipedia, the free encyclopedia
Do a ctrl+F there and search for "Life expectancy at birth" and presto:
India: Life expectancy of total population: 69.89 years
Check the CIA world factbook too if you wish (2009 estimate).
So what should I call you? Typical China liar? No, I won't. I will however tell you to stop trolling.
On second thoughts, you are a typical China liar. You would have seen conflicting figures when you googled life expectancy figures, but you chose to take the one that suits your agenda and blatantly called me a liar.
Typical China liar.
