Does this include squids and posers?
Study done by a Japanese man in a Japanese country.
This clearly only applies to the Japanese. I'm 1/4th JPN, does that mean I get 1/4th of the benefit?!
EDIT: Even if this article was true, the benefits from riding a motorcycle involving spatial awareness and memory are still limited by your daily activities.
If you spend 2 hours riding a day, and the next 10 hours doing a brain dead job and drinking a bottle of vodka before you sleep, no amount of motorcycle riding is going to make you less of a retard.
I'm pretty sure this is a cumulative thing. I've spent most of my life going from chemistry, to physics, to calculus, and now to programming. I also spent a very large amount of my childhood getting my *** kicked by my parents to play the cello (and I do it damn well). It's clear that our bodies and mind work in the simple "use it or lose it" way to preserve resources (think about muscles, what happens if you don't use them).
By the same token, I never did much physical activity when I was younger, my ****** physical coordination skills are the result of the lack of usage...maybe genetics, at least that's what I hope to be true so I sleep better at night <_<
