It&rsquo;s true! While you might feel like the same person, most of the atoms that make up your body are actually replaced every 7 to 10 years.</p> <p>Think about it like this: your body is an incredible, self-repairing, self-rebuilding machine. Your skin cells are constantly flaking off and being replaced with fresh ones, a process that takes only a few weeks. Your stomach lining? It&rsquo;s rebuilt every few days! Even your bones, which seem so solid and permanent, are undergoing a slow but constant remodeling, with old bone tissue being broken down and new tissue being laid down. This entire skeletal turnover can take about 10 years for a complete refresh. And your liver cells get a complete overhaul every year or so.</p>
