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 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.

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.

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.

Most scientists will get serious media exposure about twice in their entire career. And they'll get that because they've actually done an experiment that was interesting.

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.
