The moment I shared this news with a friend, she was quick to point out we will get back to being monkeys. Yes big fat old monkeys. The only thing that differentiates us from the rest is the big lazy brain we are all blessed with. If that start shrinking we might get back to being monkeys, reverse evolution. Older one gets, more the monkey he or she will be.
The research involving 94 people in their 70s showed that people with higher body mass indexes had smaller brains on average, with the frontal and temporal lobes – important for planning and memory, respectively – particularly affected.
