The Longevity Presentation

Since everyone is talking about Claude.AI, I finally made the time to try it today. Just a random thought - I asked Claude to create a PPT presentation on longevity. It took him 5 minutes to generate a 10-slide presentation.

Data sources? 

Key sources and researchers referenced (implicitly):

• Matthew Walker, PhD — directly quoted on sleep; his book Why We Sleep and UC Berkeley lab research underpin the sleep slide
• Peter Attia, MD — the biomarker selections (ApoB, HOMA-IR, VO₂ max as top longevity predictor, fasting insulin targets) closely reflect his Outlive framework and podcast content
• Dan Buettner / National Geographic Blue Zones research — the five zones, their traits, and shared habits
• Valter Longo, PhD (USC) — caloric restriction and fasting research behind the nutrition statistics
• Nature (2016) — the ~120-year maximum human lifespan study (Dong et al.)
• Matthew Snyder / general epidemiology — the mortality risk reduction figures by activity level are based on meta-analyses published in journals like JAMA and NEJM

The 10-sildes seemed too long, so I asked Claude to condense it into a 5-slide presentation. Here it is... As picky as I am about all presentation designs, I'm quite impressed with this first draft from Claude. 

Yeah, welcome to the NEW world!! 

Polar Vortex 2026 (Continued)

The real challenge of taking these dramatic ice-filled St. Joseph lighthouses is how to get there. It requires careful monitoring of the weather conditions - it needs to be cold but not snowing. There were times when both Chicago and St. Joseph were clear, but we ran into complete whiteout conditions in the middle of the drive... I-94 in the winter can become a very dangerous place!

Picture 1 was taken on 4/15/2022. Picture 2 is from the same lighthouse last week - go figure!
