Episode notes

Aging could be seen as a disease that is treatable and have underlying root causes. Senescent cells are one of the hottest fields in gerontology trying to do something about aging. They're an anti-cancer mechanism because if while the DNA is being copied, you make mistakes which can be dangerous or even lethal. And so you want to stop cells having the capacity to do that, start with new stuff. When these cells leach out, when they leak the stuff into the collagen and get rid of the collagen in places, they leave gaps in the tissue. Sometimes there's little bits of cancerous cells that are hanging around in the tissue,. kept in check by firm young flesh

Why should we stop ageing? Today we talk about everything to with ageing, why it occurs, why there’s renewed interest in it and what we can do about it. Sue beautifully lays out the history of longevity research, the origins of this fascinating scientific discipline and what the latest research means for you.

We’re taking a short break on the podcast this week so we’re diving into the rich archives of The Doctor’s Kitchen Podcast to resurface one of my favourite conversations from 2 years ago.

Sue Armstrong is a writer and broadcaster specialising in science, health and development issues and author of one of my favourite books on longevity, “Borrowed Time – The science of how and why we age”.

Today we discuss how Sue's career got started as well as her experience reporting on Nelson Mandela’s release from prison as well as her time spent researching HIV.

We talk about:

The origins of ageing research

The different theories of why we age

Cellular senescence

The ageing immune system

Calorie restriction and its pros and cons

And lots more
