When my grounder friends look for a tent sight, given a choice, they prefer their feet a little lower than their head - something about the blood not rushing to the head makes it easier to sleep. Regardless of the "reason", slightly lower feet is the preference.
When reading about Hammock Hangs, I often read that many like the foot end to be a bit higher. The next sentences usually makes a comment about the resulting "flat" feeling.
I'm a little puzzled about this apparent Tent = feet lower, hammock = feet higher paradox.
Is it because the weight distribution of a hammock results in a "feet higher" becoming "feet level" once the hammock is loaded with a body?
