The secret to living to an incredibly old age could be far more straightforward than previously thought, as you’ll find out in this interview with a scholar at University College London’s Centre For Longitudinal Studies.

Instead of eating olive oil, walking 10,000 steps a day or never having children, Saul Justin Newman’s best advice for living past 100 is to simply not get a birth certificate when you are born. For those of us who didn’t have the foresight at the time to not ask for a birth certificate, misplacing the document is of course an option, too.

He has tracked down 80% of the people aged over 110 on Earth and has found that the most common trait they share is not a lifestyle choice so much as the fact that their date of birth has not been properly recorded – and that their real age is unlikely to be what they say or think it is. And these are the lucky ones. In fact, many of the oldest people in the world are already dead.

In the amphibian world, the ability to live a long and prosperous life often comes down to the quality of the glue you’re able to excrete. Frogs are able to produce slimy adhesives at a moment’s notice as a defence mechanism against predators, who find these gloopy prey impossible to digest and sometimes even poisonous.

Questions of migration continue to be framed in negative terms, yet there’s good evidence to show that the movement of people brings economic benefits. Europe could be a hub of migrant entrepreneurship if it worked out how to make the most of the people looking to set up businesses within its borders. We’ve been considering ways to help make that happen and at options for making universities more commercially innovative, too.
