An interview with the SENS Foundation founder: "I've always found that basic scientists who are interested in testing hypotheses think very differently from technologists who are interested in, you know, changing the world in some way. A large part of the difficulties I've had in getting my colleagues in gerontology to really understand what I'm saying is that they're all scientists and not really technologists. In this case what I'm saying is if we implement SENS properly, comprehensively, then it will actually postpone age-related ill health substantially. And we certainly don't have any data plus or minus on that because, of course, we haven't implemented it yet, right? ... 'theoreticians' or generalists are almost non-existent in biology. Unlike physics, where you've got whole departments of theoreticians trying to bring ideas together from disparate areas ... And to the extent it is known, it's given very little respect ... But the thing is, a small coterie of theoreticians in biology who do take care have a rather high hit rate. If you look at winners of the Nobel Prize in biology, you'll find a fair smattering of people who don't know how to work a pipette."
