37.
While cast iron woks are superior to carbon steel woks in heat retention and uniform heat distribution, they respond slowly to heat adjustments and are slow to cool once taken off the fire.
38.
Perching birds of the same species will sometimes roost together overnight in groups that can number in the hundreds or thousands, more so in the winter, probably for both heat retention and protection from predators.
