Darwin also suffered from chronic health problems for his entire adult life: https://en.wikipedia.org/wiki/Health_of_Charles_Darwin

"For over forty years Darwin suffered intermittently from various combinations of symptoms such as: malaise, vertigo, dizziness, muscle spasms and tremors, vomiting, cramps and colics, bloating and nocturnal intestinal gas, headaches, alterations of vision, severe tiredness, nervous exhaustion, dyspnea, skin problems such as blisters all over the scalp and eczema, crying, anxiety, sensation of impending death and loss of consciousness, fainting, tachycardia, insomnia, tinnitus, and depression."

The time integral of his suffering must be enormous. I'm a little horrified that a man so famous can suffer so much, and yet almost no one knows about it. They remember him for his achievements; but the countless days he spent in pain are forgotten.
