A team of world leading scientists have managed to reverse the signs of ageing.
If getting old, wrinkly and weak is something you are really dreading then this news might be right up your alley.
A team of experts from Harvard and the University of New South Wales claim to have discovered technology that reverses the signs of ageing.
The scientists have successfully managed to transform an old and frail mouse into a younger, normal looking one, and thanks to the team's success they have now begun clinical trials involving humans.
"We've discovered genes that control how the body fights against ageing and these genes, if you turn them on just the right way, they can have very powerful effects, even reversing ageing - at least in mice so far.
"We fed them a molecule that's called NMN and this reversed ageing completely within just a week of treatment in the muscle, and now we're looking to reverse all aspects of ageing if possible."
In simple terms Sinclair and his team are able to activate the on/off switch in genes in order make something appear older or younger. It's hoped that this will one day work in humans to restore youthfulness to our cells.
Sinclair is one of the most highly-thought of scientists on the planet and was named in Time magazine as one of the 100 most influential people in the world.
He goes on to add that early human trials have shown real promise and that one day epigenetic technology could be as important as antibiotics in extending people's lives.
"Some people say it's like playing God, but if you ask somebody 100 years ago, what about antibiotics? They probably would have said the same thing.
"Some people worry about big advances in technology and medicine, but once it's adapted and it's natural for people to live until they're 90 in a healthy way ... we'll look back at today like we do at the times before antibiotics when people died from an infected splinter."
