Life expectancy is increasing in the developed world. But Cambridge University geneticist Aubrey de Grey believes it will soon extend dramatically to 1,000. Here, he explains why.
Ageing is a physical phenomenon happening to our bodies, so at some point in the future, as medicine becomes more and more powerful, we will inevitably be able to address ageing just as effectively as we address many diseases today.
I claim that we are close to that point because of the SENS (Strategies for Engineered Negligible Senescence) project to prevent and cure ageing.
It is not just an idea: it's a very detailed plan to repair all the types of molecular and cellular damage that happen to us over time.
And each method to do this is either already working in a preliminary form (in clinical trials) or is based on technologies that already exist and just need to be combined.
This means that all parts of the project should be fully working in mice within just 10 years and we might take only another 10 years to get them all working in humans.
When we get these therapies, we will no longer all get frail and decrepit and dependent as we get older, and eventually succumb to the innumerable ghastly progressive diseases of old age.
We will still die, of course - from crossing the road carelessly, being bitten by snakes, catching a new flu variant etcetera - but not in the drawn-out way in which most of us die at present.
So, will this happen in time for some people alive today? Probably. Since these therapies repair accumulated damage, they are applicable to people in middle age or older who have a fair amount of that damage.
I think the first person to live to 1,000 might be 60 already.
It is very complicated, because ageing is. There are seven major types of molecular and cellular damage that eventually become bad for us - including cells being lost without replacement and mutations in our chromosomes.
Each of these things is potentially fixable by technology that either already exists or is in active development.
Aubrey de Grey leads the SENS project at Cambridge University and also runs the Methuselah Mouse prize for extending age in mice.

WASHINGTON – Troops conducting urban operations soon will have the capabilities of superheroes, being able to sense through 12 inches of concrete to determine if someone is inside a building.
The new "Radar Scope" will give warfighters searching a building the ability to tell within seconds if someone is in the next room, Edward Baranoski from the Defense Advanced Research Projects Agency's Special Projects Office, told the American Forces Press Service.
By simply holding the portable, handheld device up to a wall, users will be able to detect movements as small as breathing, he said.
The Radar Scope, developed by DARPA, is expected to be fielded to troops in Iraq as soon as this spring, Baranoski said. The device is likely to be fielded to the squad level, for use by troops going door to door in search of terrorists.
The Radar Scope will give warfighters the capability to sense through a foot of concrete and 50 feet beyond that into a room, Baranoski explained.
It will bring to the fight what larger, commercially available motion detectors couldn't, he said. Weighing just a pound and a half, the Radar Scope will be about the size of a telephone handset and cost just about $1,000, making it light enough for a soldier to carry and inexpensive enough to be fielded widely.
The Radar Scope will be waterproof and rugged, and will run on AA batteries, he said.
"It may not change how four-man stacks go into a room (during clearing operations)," Baranoski said. "But as they go into a building, it can help them prioritize what rooms they go into. It will give them an extra degree of knowledge so they know if someone is inside."
Even as the organization hurries to get the devices to combat forces, DARPA already is laying groundwork for bigger plans that build on this technology.
Proposals are expected this week for the new "Visi Building" technology that's more than a motion detector. It will actually "see" through multiple walls, penetrating entire buildings to show floor plans, locations of occupants and placement of materials such as weapons caches, Baranoski said.
"It will give (troops) a lot of opportunity to stake out buildings and really see inside," he said. "It will go a long way in extending their surveillance capabilities."
The device is expected to take several years to develop. Ultimately, servicemembers will be able to use it simply by driving or flying by the structure under surveillance, Baranoski said.
