Seek ye the Bridge Of Death.. no mortal man has ever crossed..
But a horizon's walk over that bridge, and you shall find the answers you desire, fair Lukeyuan.
..but I suggest you study the anatomy of a swallow (African or European.. preferably, both) if you wish to make it across the bridge. You could also use some coconuts and a dim-witted servant with various facial deformities, to help you travel there faster.
"Who would cross the Bridge of Death must answer me these questions three, there the other side, he see.."
