Buns of steel, thighs of pain

Thanks to Bonita on Saturday morning I now know what quadriceps do. Quadriceps are the muscles that prevent you from falling down the hill at the Botanical Gardens after the pram. So whilst it is the buns that push your baby up the hill, it is the quadriceps that ensure that he goes down the hill at an appropriate and safe speed. Quadriceps also assist in the clinging on to imitation horses on alarmingly fast antique steam-driven carousels (see here).
