The manual transmission is something that used to be quite common in the automotive world, with many folks learning how to drive on that exact type of gearbox. It also used to be pretty rare to find a performance-focused vehicle with an automatic - or, at least, those weren't quite as popular or as quick as
their manual counterparts. However, in recent years, manuals have begun
dying a slow death, and are quite rare today. That's particularly unfortunate, as a new study has found that -your-own gearboxes have a big health benefit to provide.
According to Japan's
Best Car Web, this new study comes to us from Professor Ryuta Kawashima (who helped develop Nintendo
Brain Age games) of the Tohoku University’s Institute of Development, and it found that driving a manual transmission equipped car can actually stimulate the brain's prefrontal cortex in ways that an automatic cannot. Through his research, Kawashima discovered that the physical sequence of rowing through the gears is particularly stimulating for the region of the brain that controls things like attention, decision making, and memory.
Driving a car with that sort of gearbox on a regular basis is even more beneficial, this study found - it provides drivers with a little bit of a "workout" that helps mitigate the effects of aging and also improves cognitive function over a period of time. This is not the case with automatics, the study found, which just aren't as engaging to operate.
Perhaps even more notable is that this sort of activity can even help ward off dementia and other aging brain disorders, which is a major problem across the globe. Trouble is, manuals are becoming
increasingly rare in today's world, and currently represent less than one percent of sales among all automobiles - meaning that for those that wish to take advantage of these health benefits, it won't be terribly easy to find a new vehicle that can offer them.
