You Can Now Stop at Least One Existential Crisis

Does the Human Body Really Replace Itself Every 7 Years?.

Perhaps, my readers have heard the myth that every 7-10 years we are essentially clones of our past selves. Well, most the cells of our bodies are replaced every so often, but our brain cells last for a lifetime. I contend that we are our brains, so this is very important information. We are not clones of past selves. Existential crisis averted. Have nice day.
