Celebrating the future is about celebrating a better world: a world in which everyone's life is easier and their health is maintained longer. It’ll be a life where there’s more time for leisure - for enriching each other’s lives rather than just running to stand still. In other words, more holiday time! So a holiday is absolutely the appropriate way to help us focus on it and make it a reality soon.

Public enthusiasm for new advances is a key ingredient in influencing policy-makers to stimulate follow-up work with suitable funding, and it can be achieved far faster now that interested non-specialists can explore new research autonomously and can also be appealed to directly by scientists.

My approach is to start from the straightforward principle that our body is a machine. A very complicated machine, but none the less a machine, and it can be subjected to maintenance and repair in the same way as a simple machine, like a car.

Wikipedia was a big help for science, especially science communication, and it shows no sign of diminishing in importance.

Basically, the body does have a vast amount of inbuilt anti-ageing machinery; it's just not 100% comprehensive, so it allows a small number of different types of molecular and cellular damage to happen and accumulate.

Some things tend not to work so well for science - things that rely on substantial written contributions by key experts are a case in point - but even there I tend to keep an open mind, because it may just be a case of finding the right formula.

The scientific method actually correctly uses the most direct evidence as the most reliable, because that's the way you are least likely to get led astray into dead ends and to misunderstand your data.
