Viva Longevity!
A former tech exec and earth scientist interviews leading researchers to find science-backed paths to a long and healthy life, free of commercial hype.
A science-first podcast focused on longevity and nutrition. Host Chris MacAskill uses his background as a scientist and tech entrepreneur to rigorously question experts, from world-renowned cardiologists to under-the-radar biochemists. The show is explicitly non-commercial, allowing it to tackle topics like GLP-1 drugs, dietary guidelines, and food fads with an unbiased, evidence-based lens. Episodes alternate between deep-dive interviews and narrative-style documentaries that investigate a specific health topic.
“The host's unique resume—from geophysics to working with Steve Jobs to building major tech companies—gives him a credible, analytical framework for questioning experts that other health podcasts lack. Its strict non-commercial stance is a key differentiator, ensuring the focus remains on scientific accuracy over product promotion.”
Who hosts this show
Viva Longevity is hosted by Chris MacAskill, a Stanford-educated geophysicist who began his career in earth sciences before pivoting to tech. He worked for Steve Jobs at NeXT, which was later acquired by Apple, and co-founded several companies, including the online bookseller Fatbrain and the photo-sharing site SmugMug. Now retired, Viva Longevity is his non-commercial passion project, aimed at making longevity research accessible and accurate by interviewing top scientists who are often too busy with research to be social media stars.

What you'll be asked on this show
As an interviewer, Chris MacAskill is direct, deeply prepared, and operates from a position of informed skepticism. He often opens by establishing a guest's core thesis or personal story before methodically probing the science behind their claims. He is not afraid to ask pointed questions about controversies, safety concerns, or potential data misinterpretations, effectively acting as a proxy for a critical-thinking audience. He frequently brings in external research or historical facts to contextualize the guest's work and pushes for practical applications of the science for a modern lifestyle.
The show alternates between two formats: single-guest, long-form interviews and documentary-style narratives where the host investigates a topic using expert clips and his own research. Co-host Michelle Cen also appears on some episodes. The production is polished, often using B-roll and historical context to frame the conversation before an interview begins.
