Everyday Brain Training

Millions people do everyday physical training / exercises. They want to keep their body in good shape.

Why a smaller number of people intentionally do everyday brain training / exercises?

• The absence of intelligence is not so visible as defaults of the physical shape.
• Everybody thinks that he / she is enough smart.
• Playing computer games is considered as a mental work.
• No time, there are other priorities.
• Lack of motivation / self-discipline.
• There are not interesting intellectual challenges to meet everyday.
•  . . .

Many types of work, games, discussions concentrate on a limited types of challenges. You can play many hours everyday, but the types of exercises are limited: just kill / catch somebody, and you do it again and again.
