The relative heat release of a person is 1 W / kg. Compare with the relative heat release from the Sun.

The energy emitted by the Sun in 1 second is 3.83 * 10 ^ 26 J. The relative heat release from the Sun (the energy emitted by 1 kg of matter in 1 s) is 1.92 * 10 ^ -4 / kg. Thus, 1 kg of the human body emits about 5000 times more than 1 kg of solar matter.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
