Scientists have come up with proof that too much thinking can be exhausting. The impact of straining the grey matter is likely to be more pronounced in older people. A team from the University of Illinois in the US carried out research on rats. They found that concentration drains glucose from a key part of the brain in the animals. However, the effect was more dramatic in older rats, whose brains also took longer to recover.

Bullshit. Human brains get plenty of glucose to compensate for that effect. They only tested glucose levels for rats. Universite of Illinois my ass!
