Actually, Bambi, I made almost the same error you did, initially. The president you left out was Lincoln, probably due to a copy/paste quirk from the web page. What I did differently was divide by 42 rather than 43, so my calculation came out to a fraction of an inch lower than the true value. Having corrected my mistake, I came up with the same result that you did.

Yep, it turns out that I didn't include Lincoln the first time I did the calculations hence the lower number which I only noticed when I double checked my double check.

The difference in the average height of men 20+ vs 20-39 is telling for a couple reasons. The more interesting is that we begin to shrink sometime in our 30s. All the presidents have been old enough to have seen some shrinkage. I wonder whether the reported heights were their maximum, the height when elected, or something else?

Shrinkage heh. Actually I am more interested in determining the optimal average height for humans as that would assist in determining the optimal height for cybermen. I think the key initial issue is becoming aware that there are problems associated with making cybermen either too small or too large. I imagine that many folk either focus on the tallest or the smallest and completely dismiss those close to the average and their view on average height is probably the same i.e. if they focus on the tallest then they want the average height to grow indefinitely, if they focus on the smallest then they want the average height to shrink indefinitely.
