U know i dont believe that medicine is quite simple as, spin your chakra... (jiraya wasnt a hokage with a village under his resposability so he can lose so much time as he wants) Second i believe that training a medic nin is nothing that can be make in 1 month i believe thats quite similar to real world where u have to study like a bookworm for years and more if u want to specialize.

Tsunade can have 3 or 4 medic nin aprentices if she wants, i believe that among the 100 gennins (+-) u can find someone as "good" as sakura to fit for the job. This would make sense, else is like having einsten teaching only one person and not sharing his intelect with anyone else, quite absurd if u want to improve overall(not only one persons selfish desire, and more if u are the best teacher who has to look for the improvement of ALL the village and villagers).

Its true that sakura has some head for studing but i still dont want to see how he masters all the organs arteries and muscles of the body in a month (i hope it takes her quite some time, if not all the medicine students that study about 7 years will cry a lot [img]i/expressions/face-icon-small-happy.gif[/img]). I believe that chakra is very importan to a medic nin and sakura lacks a lot on that and how can he improve that if she studies 8 hours a day, sleeps 8, puts her make up(his lips hair cloths etc) 2 hour, cries for sasuke 2 hours, buys flowers 1 hour, eats 1 hour... Maybe with a time jump it can be explained, who konws...

For me it doesn't make any sense how its now maybe un the next chaps tha thing get explained anda then i can understand(at least in DBZ they invent that thing that every time that they were badly injuried they boost up and became more powerful).
