First of all, there must be a healthy body, day in and day out of the disease, don't talk about any ideals, there will be left with the pain, so there must be a healthy and strong body, this is a prerequisite.
The second thing is to have money. Their own money to spend a lot of money, but also have a relatively generous savings, this state that can meet their own needs for life, but also to help their children appropriately, will make the relationship between the two generations to get along more harmoniously.
Then again, the children are in good health, work well, family life, peace and quiet, happy life. There is no need for me to worry about anything or to do any favors. The children of the third generation are obedient, smart, and don't worry. Everyone gets along very happily and harmoniously.
And then there is a favorite sport, long-term participation in sports, physical health, no problems. They themselves also play a lot of fun, very happy.
And can often go out with friends who like to be together to travel, go to the place they like to go, taste different cultures, experience different life.
The last thing is that when you have your annual medical checkup, everything is normal in your body.

Everyone has a different understanding of life and a different way of living, so there is no standard answer to how to live in old age. In my mind, old age is not a downward spiral towards the sunset, but precisely a new beginning of a better life.
In fact, old age is largely a continuation of the state of young life, it is difficult to completely cut off to come, so the best protective armor of the later years is a period of life before it comes to be carefully spent.
