Theory on Hand Seals

[Y]

I think the seals are just a focusing method. It would explain why the aging Sarutobi needed them to do fairly basic jutsus, while the fresh Hokages used one or two.

I think its more than just focusing, because naruto was focusing alot when he was fighting kiba(enough to fart) but he still had to do seals. There has to be some sort of learning curve implemented in the hand seals. Also kakashi when he does kawarmi(sp?) in the very beggining he is reading come come paradise. I doubt he was focusing really hard on the jutsu
