All chronic diseases are a SNR problem The signal (sun, earth, cold, magnetism) is fixed, evolution tuned to it over 2 billion years. The noise (electrification, artificial light, indoor living) was introduced in 1879 and has scaled exponentially since. The channel capacity hasn't changed. The noise floor has risen >2 million-fold since 1979. Every chronic disease is what happens when the noise floor exceeds the channel capacity of a biological system that was never designed to handle it.
