Thought some of you might be interested. This is from Washingtonpost, http://www.washingtonpost.com/wp-dyn/content/article/2008/05/20/AR2008052001331.html?hpid=sec-health# Conclusion, don't cut yourself with your Yonex Arcsaber rackets or smell too much Nanogy strings.
Ah.. The Mizuno Tetracross 700's shaft is made of CARBON NANOTUBE. The ArcSabers are similar; "Cup-Stack Nanotube". Hmm.. don't chip the paint off the TC700's shaft.. otherwise all the small particles of carbon nanotube will be omitted into the air and we can die from it. Haha my friend was saying before when we were only 12, that if we swung a graphite racquet with a chip somewhere.. a small particle of carbon can fly off the racquet and mix with the air to make carbon monoxide and kill us. .. obviously not. But no matter what.. don't lick the TC700/500/300's shaft..
Only longer versions of the vanishingly small fibers have that toxic effect, the study found. And further experiments must be done to prove that the engineered motes can cause problems when inhaled, the way most people might be exposed to them.
Fried chicken give you cancer. Theres even a warning label at Mcdonalds my little brother saw. It said there was a natural chemical in their food especially in fries that is known to give you cancer. But theres still people smelling, eating, and licking it everyday.
