Why do some people willingly participate in unpleasant things like regular exercise, cold showers, bland but healthy food, sacrificial restraint, and drinking lots of water, which cause a lot of annoying bathroom runs?
The short answer: Everything has a price. Good health is no exception. In exchange for long-term health, humans must endure short-term discomfort associated with the above.
In more succinct terms, “no pain, no gain.” That’s the catchphrase Jane Fonda popularized in ’80s workout videos to express that rewards are worth the work. Or as David Morris wrote in The Scientist, “The road to achievement runs only through hardship.”
In my experience, that’s the case for good health as much as anything in life. Of course, knowing that won’t make difficult things easy. But it does give them meaning, which I believe lessens suffering.
