"Somehow the cells know the body can reset itself, and they still know which genes should be on when they were young," Sinclair said.

While we wait for science to determine if we too can reset our genes, there are many other ways to slow the aging process and reset our biological clocks, Sinclair said.
"The top tips are simply: Focus on plants for food, eat less often, get sufficient sleep, lose your breath for 10 minutes three times a week by exercising to maintain your muscle mass, don't sweat the small stuff and have a good social group," Sinclair said.
All these behaviors affect our epigenome, proteins and chemicals that sit like freckles on each gene, waiting to tell the gene "what to do, where to do it, and when to do it," according to the National Human Genome Research Institute. The epigenome literally turns genes on and off.
What controls the epigenome? Human behavior and one's environment play a key role. Let's say you were born with a genetic predisposition for heart disease and diabetes. But because you exercised, ate a plant-focused diet, slept well and managed your stress during most of your life, it's possible those genes would never be activated. That, experts say, is how we can take some of our genetic fate into our own hands.''In molecular biologist David Sinclair's
lab at Harvard Medical School, old mice are growing young again.
Using proteins that can turn an adult cell into a stem cell, Sinclair and his team have reset aging cells in mice to earlier versions of themselves. In his team's first breakthrough, published in late 2020, old mice with poor eyesight and damaged retinas could suddenly see again, with vision that at times rivaled their offspring's.
"It's a permanent reset, as far as we can tell, and we think it may be a universal process that could be applied across the body to reset our age," said Sinclair, who has spent the last 20 years studying ways to reverse the ravages of time.
"If we reverse aging, these diseases should not happen. We have the technology today to be able to go into your hundreds without worrying about getting cancer in your 70s, heart disease in your 80s and Alzheimer's in your 90s." Sinclair told an audience at Life Itself, a health and wellness event presented in partnership with CNN.
"This is the world that is coming. It's literally a question of when and for most of us, it's going to happen in our lifetimes," Sinclair told the audience.

Amazingly, damaged neurons in the eyes of mice injected with the three cells rejuvenated, even growing new axons, or projections from the eye into the brain. Since that original study, Sinclair said his lab has reversed aging in the muscles and brains of mice and is now working on rejuvenating a mouse's entire body.
"Somehow the cells know the body can reset itself, and they still know which genes should be on when they were young," Sinclair said. "We think we're tapping into an ancient regeneration system that some animals use -- when you cut the limb off a salamander, it regrows the limb. The tail of a fish will grow back; a finger of a mouse will grow back."
That discovery indicates there is a "backup copy" of youthfulness information stored in the body, he added.
"I call it the information theory of aging," he said. "It's a loss of information that drives aging cells to forget how to function, to forget what type of cell they are. And now we can tap into a reset switch that restores the cell's ability to read the genome correctly again, as if it was young."
While the changes have lasted for months in mice, renewed cells don't freeze in time and never age (like, say, vampires or superheroes), Sinclair said. "It's as permanent as aging is. It's a reset, and then we see the mice age out again, so then we just repeat the process.
"We believe we have found the master control switch, a way to rewind the clock," he added. "The body will then wake up, remember how to behave, remember how to regenerate and will be young again, even if you're already old and have an illness."
