No, the body doesn’t just wear out as we get older.
Friends often look at me quizzically when I tell them this. One says, “But I can feel myself wearing down.” And another: “Nothing works the way it used to.

Aging & evolutionary biology
Josh Mitteldorf is best known for promoting the theory that aging is not “wearing out” but rather an evolved program that limits lifespan. The surprising fact that our bodies are genetically programmed to age and to die offers an enormous opportunity for medical intervention. He began blogging about aging on this site in 2012. His guidance for a long life is at AgingAdvice.org. His two books on aging are available at Amazon and elsewhere.
Mitteldorf’s PhD is in astrophysics. Since about 2020, he has taken up a new challenge as curator and critic of science on the fringe, writing about promising science that the science establishment has unjustly neglected.
In other areas of life, Mitteldorf’s two daughters were among the first girls to be adopted from China in the 1980s. He has taught a weekly yoga class for fifty years. He is an avid amateur musician, playing piano in chamber groups, French horn in community orchestras. Follow his other writing at mitteldorf.substack.com, and listen to his poetry on YouTube.
