Chill out SG.
My wife is Japanese and my son is half Japanese, I didn't feel this was offensive or nasty at all.
If we get too PC we won't be able to say anything or make jokes about anyone anymore.
Plus this comment is mostly saying that Japanese people and Asians in general tend to age much slower than westerners. Which is not a negative thing and stereotype or not its clearly true for the most part.
ETM also said there are more cute Japanese girls per capita than any place hes been to.
Find me a Japanese woman who objects to this statement.
Most of my English buddies have beer bellies, lots of grey hair and some balding (mid thirties).
My Japanese buddies would mostly have to pull out their ID in Europe to buy alcohol
Thats just how it is.
Probably diet is important since I also have none of the issues my English buddies of the same age have
Aside from this check the vids I posted, some good riding and some really good ground tricks too (although the crazy spinning is not my thing).
