Nunchucks? or Nunchakus? Chainsticks?

The Nunchaku (Japanese: ヌンチャク Hepburn: nunchaku?, often “nunchuks” or “chainsticks” in English) is a traditional Okinawan weapon consisting of two sticks connected at one end by a short chain or rope. It was used by Okinawan nobles rather than rebelling peasants, but was not a popular weapon since it was not efficient against the most widely used weapons of that time, and few techniques for its use exist. The two sections of the weapon are commonly made out of wood, while the link is a cord or sometimes a metal chain. The nunchaku is most widely used in martial arts such as Okinawan kobudō and karate, and makes for a good training weapon, since it allows for developing quicker hand movements and improves posture. Many varieties of nunchaku are available.

In modern times, nunchakus (Tabak-Toyok) were popularized by Bruce Lee and Dan Inosanto in their respective movies. Organizations like The North American Nunchaku Association, World Amateur Nunchaku Organization, Fédération Internationale de Nunchaku de Combat et Artistique, World Nunchaku Association and International Techdo Nunchaku Association teach the use of it as a contact sport.

Modern day nunchaku can be made from metal, plastic or fibreglass. In addition, toy and replica versions are available, made of styrofoam or plastic. Except for use in professional martial art schools, possession of this weapon is illegal in some countries.

Eat right and exercise. Finish your veggies, like your mom told you.

This is a fantastic question and I wish I had the smarts to ask it when I was 23 – instead I wasted a truckload of time, money, got married to the wrong person and also didn’t understand (or learn) the fundamentals of an enduring relationship.
With that being said I really recommend reading and applying all that you can from a very special book called How to Win Friends and Influence People by Dale Carnegie.
Also one of the best and most entertaining books on Male/Female relationships is called Why Med Don’t Listen and Women can’t Read Maps by Allan and Barbara Pease.
Money, money, money…you want to learn to be it’s master and not it’s slave. The book – The Richest Man in Babylon is a great start and also learning about Gold and Silver. Here is some of the best info you will find (super interesting to watch too) Silver & Gold – Hidden Secrets Of Money Ep 1 – Currency vs Money – Mike Maloney
-Learn computer programming
-Do some SERIOUS volunteer time for 6 months. I’m talking 20 hours a week outside of what you do
-Develop a strong friendship with someone new every 3 months. I’m talking best friend level. To do this, tell a girl you love her, she will be like “we should just be friends”.
-Do something really hard for you and fail miserably at it. This will teach you how other’s feel when they get in over their head in trying to learn something that will make them a better person.
-Learn Kickboxing, not the “black belt” kind, but the serious kind that you could use in a jam
-Learn NLP. Neuro Linguistic Programming
“How you do one thing, is how you do everything” Do anything with tenacity.
First, you have to learn about yourself. Know what you’re good at, what you have to offer, and what you want out of life. This is the only way to know what you can do now that can help you in five years. A general direction.
Second – generally, go out and meet people. Learn to communicate and build strong relationships. It helps you build empathy, a larger ‘lens’ to look at the world, support for yourself, support for others.
