Longevity, biohacking, peptides, supplements—social media is full of promises about how to live longer. But how much of it is actually backed by evidence?

In this episode of I Did My Own Research, Dr. Fran is joined by geriatrician Dr. Stephanie Rogers (Age Well with Dr. Steph), Associate Chief of Geriatrics Clinical Programs at UCSF. Together, they unpack what actually helps people age well—and what the internet is getting wrong.

They discuss why “longevity medicine” often misses the bigger picture, the reality that most of us will experience some level of disability if we live long enough, and why building healthcare systems and communities that support aging is just as important as trying to extend lifespan.

Dr. Rogers also breaks down common medication pitfalls in older adults, including surprising risks of medications, and explains why some widely used drugs may be doing more harm than we realize.

The conversation also dives into:

• Why biohacking and supplements are so appealing online
• The difference between lifespan vs. healthspan
• How doctors actually learn from each other on social media
• The biggest predictors of aging well (hint: they’re not peptides)
• Why hearing loss, muscle mass, and social connection matter more than most people think

Plus, rapid-fire questions on the most harmful medications for aging, underrated longevity habits, and the best things you can start doing in your 30s and 40s to age well.

If you’ve ever wondered what actually matters when it comes to longevity—and what’s just internet hype—this episode is for you.
