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.

There is no difference between saving lives and extending lives, because in both cases we are giving people the chance of more life.

The aim is to postpone frailty, postpone degenerative disease, debilitation and so on and thereby shorten the period at the end of life, which is passed in a decrepit or disabled state, while extending life as a whole.

It's not just about life, of course; it's about healthy life. Getting frail and miserable and dependent is no fun, whether or not dying may be fun.

The biggest handicap in research is an ability to think outside the box. The handicap is being encumbered by all the conventional wisdom in a given field.

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.

If changing our world is playing God, it is just one more way in which God made us in His image.
