The world's best juggler is a roof tiler.
Anthony Gatto holds 9 juggling world records. The difference in complexity between 7 and 10 rings being juggled is staggering. Juggling 7 rings he did for 15 minutes. The 10 rings for only 47 catches.
As with that paragraph: Seeing him do this is a blur. It all looks the same. Equally impressive and somewhat boring after a while.
He is aware of the complexity and skill that he has. So is his peers. It takes an expert to appreciate a true expert.
Anthony Gatto retired in 2012 and now runs a roof tiling business.
