>You must remember though that there is a difference between correlation & causation.
Yes, I think I hinted at that. My (primitive) understanding of statistics is this:
A correlation between "A" and "B" is found.
First of all, it must determined whether the correlation is "statistically significant". That is, the deviation must be large enough. How large, depends on the size of the population.
If the correlation is statistically significant, it is still up to the statistician to guess whether "A" causes "B", whether "B" causes "A", or whether both are caused by an external factor "C". As in your example of big feet.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
