Lan Ze and Lanhua are indeed very tender. Whether they are fat or thin, their bodies seem to be filled with abundant moisture, and every inch of their skin is full. This is how young people are.

"You are probably at least seventy-five?" Orchid tried to guess. "It seems that you are in good spirits."

"After eighty?" Lan Ze also guessed that the old director's body was already very aging. However, if he could take on the position of director of the institute, the old man's physical strength and energy must be pretty good, and he shouldn't be particularly old.

"I am the same age as your father." The old director said with a smile, "My birthday is only a few days away from your father."

Lan Ze and Lanhua looked at each other. They only knew that their father was 60 years older than him, and this year was 92, and they didn't know when his father's birthday was. To be honest, this was a bit embarrassing.

Fortunately, the old director continues to say:

"Everyone in our hometown lives very long. My mother lived to be 106 years old. My father lived to be 104 years old. I have a distant aunt who lived to be 121 years old. How about it, isn't she quite amazing?"

Lan Ze and Lanhua nodded quickly. Momo saw it and nodded heavily.

"Look at me, I'm in good condition now, right?"

"Very good. healthier than many elderly people in their seventies and eighties." Lanze replied affirmatively. "I have taken care of the elderly before."

"Then my current state, how about the airship?" the old director asked with a smile.

"Is it too forced?" Lan Ze said without hesitation.

"Lan Xianyin's state, how about the ship over the air?"

"The state system does not allow it."

"Look, even you know very well. If I can't get on the air ship, I can't get on it. Your father can't get on the air ship, the system does not allow it."

"You..." Lan Ze wanted to grab his head, but he felt it was inappropriate, so he had to rub Mo Mo's little head, "What are you comparing with my dad?"

"Why can't I compare with him? I'm the same age as him."

The old man in front of me is like a child who can't get fun toys. He is a little willful.

"How can he compare with you in his social status and influence? He knows how to play all day long and has no serious things at all."

"I want to play too. Hum... I can't play anymore."

Speaking of this, Lan Ze felt that he could not take the lead. He glanced at the old director's body. Although it was tall, it looked more like a hard machine made of bones and skin filled with a small amount of muscles.

A normal creature should be a softer thing. Little babies can take their feet to their mouths and chew them casually. When they grow up, the feet that can be chewed casually are pig's trotters. But at least adults are quite flexible in bending over to pick up something. However, as they grow old day after day, they become cautious when they bent over and wear shoes.

So, what the old director said was probably the truth.

Although I don’t know what the elderly want to play, people of all ages have the freedom to play.

Orchid's expression was serious and he didn't know what he was thinking.

"You can see that. My father and you are old. But our living conditions are completely different. Research on longevity began centuries ago. Human life span has a lot to do with the incidence of several metabolic diseases. In different races, there are people with natural immunity to these common diseases. We have discovered these a long time ago."

"These are no secrets. The prevention and treatment of metabolic diseases are enough to increase the average life expectancy to nearly one hundred years." The old director continued, "But the super-aging society in China has given us a warning. Longevity itself is meaningless. Survival, but physically disabled people cannot provide labor and brain power. Don't refute me. There are very few healthy people like me who are not disabled. I live to the age of 90 and still have no deaf ears or eyes, which is also due to family inheritance."

The old director sighed: "Some people start to survive in their slightest age. Most of the elderly are around 80 years old, and their bodies are gradually disable and their ability to take care of themselves. Even with the assistance of medical institutions, they can survive, and the human body itself is aging with age. From the inside out, it is unstoppable.

After the age of 80, most of the elderly who do not rely on medical institutions and can still take care of themselves have one or two genes related to longevity. Such as those passed down from my family, but they are quite valuable."

"In our era, technology is becoming more and more complex, and children's years of education are getting longer and longer. The journey of interstellar travel is getting longer and longer. Young people who complete education and enter various jobs are generally nearly thirty years old. Therefore, the genes that can extend the life and work years of workers are of great significance to us humans entering space."

"The gene you are referring to..." Lan Ze accidentally said.

"There are two routes for a long life. Do you want to know?"

Lu Lulu came in from outside with a large tray. She put the tray on the tea table, arranged the cup, poured the good tea, and smiled sweetly at the old director.

"Yes." The old director nodded with satisfaction. "Go and prepare the information."

So Lu Luo turned around and entered one of the rooms connected to the small living room, next to the director's office.

The old director picked up the teacup and took a sip of it to moisten his throat, and then said, "In addition to the useless longevity, there is another route, which we call "Unold".

"I have been following your father's condition. It has been forty-two years since then." The old director put down the tea cup. "The antioxidant properties in the cells were also recorded as a long-lived mutation. But over the years, he has surprised me more and more."

"I think I should be fine if I live for another ten years. After all, my parents are over 100 years old. And I don't have any bad habits in normal times. However, they are only living for a little over 100 years. So, I guess I can only live for about ten years."

"But your father, this old man Lan." The old director showed a subtle smile. "I judge that he is likely to be over 100 years old. But even if he lives less than 100, what does it matter? He is over 90 years old and has a heart of thirty years old. He has never had any common problems for middle-aged and elderly people. His physical functions are still young and he can do anything he wants. With such a high quality of life, it is worth dying early."

If the person who was speaking was not an old man in his 90s, Lan Ze felt that this was cursing his father to die early.

If you think about it carefully, your old man is already over 90 years old. If you continue to live, no matter what year he dies, he will not die early.
