When I was younger I was thoroughly unimpressed by "adults chasing a ball". Getting older, while still not a fan, I've become amazed at the stuff these bodies can do. An 80kg person taking a split-second decision to jump one/ one and a half meter into the air, rotating more than 90 degrees so that their legs are actually above their heads, reaching a ball travelling at a 100km/h and hitting it to send it on a target, then falling flat without hurting themselves, just to get up and start running again? Just wow.
