Are anime's somewhat realistic? no.
Considering anime's such as "DBZ", "SEL", "Evangelion", and any other sci-fi, I'd have to say: "Absolutely not. If you think they're realistic, you'd have to be insane."
But, considering all anime, I have not seen one yet that is realistic. Same goes for any tv program out there. The only realistic tv program would be about someone watching tv and playing on his pc all day. Maybee going out to work or meeting up with his friends every once and a while. You will never see a tv program with a character watching tv for an extended period of time. (*in america, ive seen anime do it though)
So, in ending, there's a lot of do's and dont's of wood repair. Just remember: When in doubt, pull it out.
