#ad Nunchaku laws: are nunchucks legal in your state? The book's answer: it depends on where you are. Nunchuck laws are scattered across state codes, territorial laws, federal rules and city ordinances. "Not identified" is not the same as "legal." Chicago is stricter than Illinois. TSA doesn't allow them in carry-on bags. Three states once banned them: Arizona, California, New York. Swipe through, then save it before your next trip. Nunchaku Laws covers all 50 states, plus D.C. and U.S. territories. Book 2 of the Nunchaku Mastery series. Search "Nunchaku Laws" on Amazon, or link in bio.

“I don’t like to exercise… what are the alternatives?” Osteoporosis. Wheelchair. Hip replacement. Insulin resistance. Walker. A fistful of pills every morning. Also: type 2 diabetes, hypertension, heart disease, visceral fat, sarcopenia, osteoporosis, metabolic syndrome, depression, cognitive decline, certain cancers, stroke risk, chronic back pain, sleep apnea, joint pain, and chronic inflammation… That’s the alternative.
