Vitamins 'could shorten lifespan'

[Niels Bohr 72]

Interesting.

I can't rely on small population samples since it doesn't truly give a bell curve based on a population of 300 million people. It's nice how they have worked out the calculation based on a sample size of 181,000. Percent error is high on such small population size.

This information is only for reference and it's not intended to be used to give conclusive result. It's only to show people some numbers that may or may not help them in the future. Research surveys like these are very difficult to do since it requires so many years to observe all the 181,000 sample (people). And, not everyone within that sample have the same biological makeup. Plus, there's no way in knowing whether the sample followed the rules given by the researchers. It's all based on trust in this case.
