Connection between life spans and calories

Do you want to live long? Yesterday, I watched a program whose theme was “life spans”. “Life spans” means how long we can live in the future. In the program, a professor lectured on the theme to TV stars. According to the professor, there is close connection between life spans and calories (quantity of how much we ate foods). The professor said that the more we gain calories, the shorter we can live. So it is important to control calories. If we stop eating to the extent of 60~70%, our life spans will increase, the professor suggested. Many animal-experiments which have been carried out by scientists have proved this fact. The professor also implied that it is important to get exercises. By exercising, we can work “Life-spans-cells” inside our body and the cells prevent us from aging. There is another positive aspect on controlling calories. We can keep our skin young and clean by this. This is good news for not only women but men too. So anybody who wants to live long and keep your skin young should control calories and take exercises!!
