Juggling is one of my hobbies. Although it takes more practice than it seems. It's one of my favorite things to do during the day if i don't have work to do. I simple get 3-4 balls and i start juggling them around. They're very entertaining. At times i could juggle for like 3 hours and i wouldn't even feel the time.
I watch a lot of shows where famous professional jugglers like Michael Davis demonstrate incredible skills at juggling and i hope one day i would get to even half of their skills. :)
