Not the years, it's the mileage

My daughter and I have this game we play when we're going down the front steps at home. I pick her up - at forty or so pounds, she's not too heavy yet - and bounce down the steps. I step quickly, exagerrating her motion so she bounces, a bobber on a suddenly rough lake. Stand at the top of the steps...sway backwards just a little...start the lean forward...bouncebouncebounce.
