You know that expression, 60 is the new 50? Well, it turns out that may be true.
At least when it comes to your brain. Over the past several decades, humans have been getting smarter, and now scientists say today's tech gadgets probably play a big role in that.
In fact, scientists at the International Institute for Applied Systems Analysis have found that 60-year-old people in 2012 had the same mental skills that people in their early to mid 50s had in 2006. They're not just talking about IQ, either.
Human IQ has been going up at least since the 1930s. That's called the Flynn Effect, which says improved IQ is due to better schools, good nutrition and more mental stimulation, from things like school and work.
In this new study, scientists also test for verbal fluency and cognitive functions. The coolest part of their findings is that the strongest correlation they've found to explain people's younger brains is the increased use of technology, like computers and smartphones.
Scientists say computers and smartphones improve our brains with positive mental stimulation. Meaning, computers and smartphones are challenging, and fun.
