Why do we wrinkle, slow down, and creak with age, and is there any way to hit “pause”?
In this episode of Explain It Like I’m 5, Alex breaks down the science of aging in the simplest terms possible: from the Hayflick limit and telomeres (your DNA’s shoelace caps), to oxidative stress, cellular “garbage,” and a tired immune system. We’ll explore why evolution doesn’t bother keeping us young forever, the wild science of anti-aging research—from telomerase and senolytics to CRISPR—and why lifestyle still beats miracle creams. Plus, discover the weird quirks of aging (like why grandpas have big ears and lobsters basically don’t age at all) and why growing older isn’t just decline—it’s also growth, wisdom, and a surprising boost in happiness.
