Q: JKD (Jeet Kuon Do)These are the best ones closest to my areaand i want to know which one is the best in terms of fighting (got the most effective and powerful swift moves)also one which has the best weaopn training and teaches you good trapping and pressure point techniquesWhich is the one which is shown in the movies most and what movies You dont need answer all of them just the main question which one of these are the best for fightingthnxxx
Er... fake-ish. Any approach that emphasizes stand-up combating and have an impact on-most effective approaches would not have as well an reply as grappling/groundfighting techniques, however hitting any person is larger than not anything in any respect. I additionally do not suppose that the majority streetfights turn out to be at the floor, except you imply one fighter finally ends up at the floor upon getting sucker-punched. And kung fu is a beautiful extensive time period, and it isn't a well concept to color all Chinese techniques, of which I was once as soon as informed there have been over four hundred distinct varieties, with the identical brush. Some techniques, corresponding to puppy boxing, truthfully revolve round a downed opponent attacking a status opponent. But if you are pronouncing that finding out CMA's won't make you a well groundfighter, I agree.
Q: I have been doing a science projet and i cant find it anywhere
The wild Whooping Crane flock spends its summers in Wood Buffalo National Park in the Northwest Territories of Canada. They nest and rear their young there. During the fall season, the Whoopers migrate 2,500 miles south to Aransas National Wildlife Refuge in Texas where they spend the winter and early spring. There are currently 193 birds in this flock.

Q: My fiance and I would like to make 1,000 paper cranes for our wedding next year in May. We are looking for a good type of paper to use for this. We are not too particular on the color of the cranes, though we like blue or gold. Does anyone have any feedback on the sort of paper I can get for this project? I know there is origami paper I can buy, but I was wondering if that is the only option I have to choose from. Thanks in advance! :)
I okorder Hope this helps!
Q: I'm just curious about it, and i need it for a fan fiction story i'm writing. thanks ^__^
Yes. It is genetically coded into japanese children before birth. As soon as they are born they know how to fold paper cranes. But it takes a couple of years for them to develop the hand coordination to actually do it.

Q: Something confuses me in dragon ball:When roshi has a flash back, he says crane didn't turn evil until after mutaito fails to kill piccolo, but in the filer where goku goes back in time, crane is an asshole before picolo and roshi referred to him as a friend before the piccolo incident.Also, why in the piccolo flash back are roshi and crane bald but in the filler do they have hair and glasses?Also, why in the filler does crane have a different outfit in the filler than the other students but in the piccolo flash back he has the same outfit as roshi?
The idea is that Crane Hermit is a selfish man that would do anything to get what he wants. In the past, Master Mutaito was there to ram some discipline in his head and have him under control. Following the events of his death and the defeat of King Piccolo, nothing could really stop him from being a selfish jerk again. Roshi probably didn't mention Crane being bad before King Piccolo's arrival because he wasn't really evil before it either. He was selfish and greedy, but not outright despicable as later... at least not that much. Roshi seeing Crane as a friend might imply that Crane had some redeeming qualities during his years as Roshi's rival under Mutaito's guidance. About their baldness, I think they shaved their heads after a while due to how monks and some martial artists tend to shave their heads. That or it's a plot hole due/filler error. It's again either a plot hole/filler error or they just switched outfits once they reached a certain level of their training, just like how you gain a different color of band as you progress in Judo and Karate.
