I think it’s very important in human life that we grow up by learning, for example learning English, researching history, writing and computing and so on.

Until middle-age, people have to do a lot of things in their daily lives, such as work, childcare, making friends.

However, in old age, they get a few things which are walking, reading, listen to music, watching TV. Most of them have to give up active sports, although some relatively rich people go to the gym.

There are some people lose their dreams because of repeatedly simple and boring lives each day.

But if they continue something to study till last day, they can find out shining little stardust as forget about many worrying events such as disease, accidents, loneliness, death.

Unfortunately, after a while as they are almost forgetting the findings, it would be better put it on paper.

It is wonderful getting into something.

Happiness depends on us.
