In recent years, it has become far more normal for lots of countries to show a longer life expectancy than in the past. While there may be some benefits for current society, this can contribute to having exact problems for the governments, I think.On the one hand, having lots of elderly folk in our community who do not wish to learn their own history may be useful. It might be important to prevent the community from losing its imagination about Marvels in history, whose heroism still provokes the young generation to be the leaders of their society. Another one is to maintain customs passed down from the past until now as a result of historical events. There are unchanged traditions, such as being respectful to ancestors, where old people live more.
