That's incredibly misleading and a fantastically blunt example of correlation not implying causation. Do you really think Indian Independence was the only factor over a 60 year period responsible for that 33 year life expectancy increase? It's what you comment appears to say. I'd still believe your (implied) argument considering that it was likely that after Indian Independence the people were more able to get access to modern medicine and distribute it effectively, but without including some comparative estimate those data points are particularly biased and misleading.
