This is a dude who grows up to make giant armor come out of his eyes that can slice mountains in half, a kid who grows up to be able to pull down two meteors from outer space... and he can't skip a damn rock across a river?? I mean, kids his age train to fight with swords, throw knives and giant stars while jumping through trees, fight in war and stuff... and he has trouble skipping a rock? ... And life expectancy of 30? Lol who's the leader of the Statistics Clan specialized in data anlysis jutsu that went around and conducted that study? "Excuse me, Mr. Uchiha. What are the names, ages, and gender of everyone Hashirama and co. killed today, if you don't mind?" Uchiha: "Fuck off! Katon: Goukakyu no Jutsu!" "Lol katon... Is this a bad time for you? I'll come back later." Uchiha: [sigh] "... sure." Spoiler: Just havin some fun on things that took me out a bit.
