Hey, future mamas and curious readers! Buckle up because scientists just dropped some jaw-dropping news that's gonna make you go "Wait, what?!"  So, there's this team of smarty-pants at Columbia University who've been playing detective with our DNA. They've been peeking into what happens to us ladies when we go through pregnancy. And guess what? It turns out, having a baby might just speed up our body's clock! Tick-tock, right?

Here's the scoop: these researchers looked into the lives and DNA (that's the stuff that makes you, you!) of over 1,700 people. They had a special spotlight on 825 women, tracking their pregnancy stories. And bam! They found that each time a woman gets pregnant, it's like her body's clock speeds up by two to three months. Imagine that – every baby brings you a bit closer to becoming a wise, old owl.
