The director of an assisted-living housing complex was puzzled by the following situation. When she let the residents choose their own dinner time, as well as what they wanted to eat, she realized there were far fewer health problems and deaths. To what might she attribute this?

I think the answer to your question is perceived control. I hope this helps.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.

frequency is the answer
