Average Adult Human
7 octillion atoms of questionable decision-making/The Human Body
The average adult human stands about 1.7 meters tall, weighs roughly 70 kg, and contains enough water to fill a medium bathtub. The body generates about 80 watts at rest, roughly enough to power a laptop, and maintains a core temperature of 37°C with obsessive precision. We are, essentially, temperature-regulated water balloons with opinions.
