I think it's reasonable to suppose that one could oscillate between being biologically 20 and biologically 25 indefinitely.

Ageing is, simply and clearly, the accumulation of damage in the body. That's all that ageing is.

The right to choose to live or to die is the most fundamental right there is; conversely, the duty to give others that opportunity to the best of our ability is the most fundamental duty there is.

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

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.

I'm the chief science officer of a foundation that works on the application of regenerative medicine to the problem of aging.

Theres nothing wrong with making the best of ones declining years, but what does annoy me is the fatalism. Now that were seriously in range of finding therapies that actually work against ageing, this apathy, of course, becomes an enormous part of the problem.
