Social isolation and loneliness increase mortality risk by 26-32% — comparable to smoking 15 cigarettes per day. This is not a soft finding; it appears in large meta-analyses across multiple populations. Strong social connections are one of the most consistent predictors of longevity, yet this intervention is almost never discussed in longevity circles focused on molecules and devices.
The full evidence review — including the free intervention that reduces mortality more than any supplement — and why nobody in longevity talks about it — is in Section 11 (Mindset & Social Connection) of The Anti-Longevity Playbook.
