anyone under 6'2" should pause and contemplate the implications of that.
Um, I don't think you're using this correlation correctly. Because we have a model where nutritional deficiencies lead to both short height and low IQ, the amount of information we get is dependent on where we are in the height and IQ spectrum. Basically, if you're uncharacteristically short, say -2 sigma or lower, then you should be worried; if -1 sigma or lower, a slight suspicion; 0 or higher, little information, rather than the "if you aren't more than +1.3 sigma, contemplate."
Except that this correlation is much less informative than, say, IQ tests.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
