re:this soft growth of hair as bumfluff and the Xrefer thread--

in US its peach fuzz at least most commonly- but i have heard young boys described as "having no more beard than a newborn's bottom"

lots of baby's get born hairy-- i don't know why or what percentage.. but its not uncommon to see new borns covered with down hair. by the time they are a month old or so, it goes away..
