Think...

The best way to keep a body in shape is for a person to "exercise". Although I don't do much of exercise myself. In any case, what is the point of exercise? It is definitely not like if you exercise 1 month and you become fit, the next month you don't do any exercise and you're fatter than you originally were... The point of exercising is continuous movement. And this continuous movement helps the food you eat get to the muscles that are working so hard.

Just as it is with the body it is the same with the mind. People do not do mind exercises and claim that they are just not clever enough. Most people do not want to do mind exercises, just as they don't want to do body exercises. Most people sit and watch TV thinking that this will help pass time. The only thing that happens during this time is the person's mind gets focused onto something which might be destructive/constructive depending on the movie/show/etc.

A super-power is not a super-power until and unless there are great thinking minds behind them. When the mind is compromised the power is compromised.

Then again, "Knowledge is power", but without a mind to fully understand the knowledge and to convey it properly; Knowledge is useless...

If mind exercises are done continuously, the mind will get better than the body which will only make the person smarter but can obviously turn the person into a bloat. Therefore equal balancing of mind and body exercises can make a better person out of you.
