On-line, I learned this:
A whopping 41% of participants [in a survey] sleep in this curled-up manner. Women are twice as likely to rest like this and it is listed as the most common position. These sleepers are said to have a tough exterior but are still sensitive and may appear to be shy but warm up quickly.And this (at a great website, 1000 Awesome Things):
The fetal position is the best way to keep warm if you find yourself tentless in Nunavut or crashing on a pal’s basement floor without copious blanketing. It literally warms the heart (liver, lungs, and kidneys). And hey, isn’t the fetal position just one more way to turn back the clock? After all, your body knows the fetal position, [and] your body lived the fetal position...Plus this:
The fetal position has been observed in drug addicts, who enter the position when experiencing withdrawal. Sufferers of anxiety are also known to assume the fetal position during panic attacks.But type this question into Google, with quotation marks, and you get no hits: "Do our bodies remember being in the fetal position?"*
