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

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

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.

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.

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.

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

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.
