<b>From a celebrated team comes a fascinating look at why we don't have super powers (alas) — and why size matters, for creatures big and small.</b><br><br>Did you ever wonder why there are no high-fl ying, wall-climbing, tall-building-leaping superheroes in real life? Find out what keeps big animals (like us) from engaging in astonishing feats of strength and agility, and yet why being tiny and all-powerful might have a downside. What if you could lift fi fty times your weight (hello, ant), but getting wet could kill you? Or you could soar like a bird, but a cold breeze would do you in? Whether big or small, our size defi nes more about us than we could ever imagine. Join the duo that brought us POOP, EXTREME ANIMALS, and WHAT'S EATING YOU? for a fun and intriguing exploration of what it means to be just the right size.
