What is the first sentence of the age mystery?

Some people on the internet say that the highest level of a person's "showing off his wealth" is his invincible figure, and his age is a mystery. A person's real wealth is not to see what house he lives in or what car he drives, but to see you standing among a group of elderly aunts, hot and charming, and as beautiful and young as a girl.

But I don't think so. I think a person is really rich, not materially, but spiritually. No matter how you maintain and exercise through external means, it is an external thing. Only when a person has profound knowledge and rich spirit can he look at life calmly and face the laws of nature.
