Doing so is important in my view. For example, the oft-cited average US male height 5&amp;#x27;9 or 5&amp;#x27;10&amp;quot;, but for white American men it&amp;#x27;s more like 5&amp;#x27;11&amp;quot;</text></comment>

They tend to grow taller in North America (not just second generation), again, unsurprisingly because of diet.</text></comment>
