The claimWhat Michael actually said
In a People cover story shared by his foundation, Fox described how he sustains a positive outlook after decades with Parkinson's, saying optimism grows out of gratitude and leads to acceptance. He framed it as a practice he keeps returning to, not a fixed personality trait.

- Lee et al., PNAS, 2019, higher optimism predicted longer lifespan and greater odds of living to 85 across two large cohorts
- Rozanski et al., JAMA Network Open, 2019, meta-analysis of 15 studies linked optimism to fewer cardiovascular events and lower all-cause mortality
Why it mattersWhy this matters for longevity
Mental outlook is often dismissed as soft, yet it shows up as a measurable signal in serious mortality datasets.
Framing optimism as a gratitude practice makes it something people can work at, not just a temperament you are born with.
The evidenceWhat the science says
In two large cohorts, the most optimistic adults lived meaningfully longer and were more likely to reach 85, and a meta-analysis of 15 studies tied optimism to fewer cardiovascular events and lower all-cause mortality.
These are observational findings that cannot separate optimism from other advantages optimists tend to have, and the studies were not done in people managing a chronic neurological disease, so the size of any real effect for someone like Fox is unknown.
TakeawayThe honest takeaway
The practical lesson
Practicing gratitude to build a steadier outlook is safe and free, and the population data suggest it travels with better long-term health.

SupplementsThe supplement angle: Omega-3s and vitamin D
Support a habit, do not replace one
Some research links omega-3 status and adequate vitamin D to mood and brain health, but neither substitutes for the psychological practice Fox describes, and no supplement has been shown to manufacture optimism.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
